I am in my final year in ee and now i want to do some projects on matlab simulink..can someone help me out to basic to advance projects on matlab

Yo, I recently got MATLAB and wanted to test some theory. I used a PDE method to perform an FEA analysis to compare it with my theory. I need your help ladies and gents, how does one visualise the maximum stress values, both principle and Von Moses if possible? Thank you.

So, im a first time poster so pls be kind :) Also english isnt my first language so excuse any mistakes in my writing

Anyways, I just started my masters in computational mechanics, and I only had some basic knowledge on the subject from my postgrad (plus I only know C++, Matlab and theoretically fortran but not really). They just told us to write a code with a basic grid (like 3x3 or 3x4) and create a NOP(I,J) function, where I is the number of elements (square elements), J is the number of local nodes (J=1,...,4), and the output should be the global node corresponding to a specific local node of a specific element or something like that. Forgive me if the explanation is garbage, I understand it theoretically but not 'computationally' per say.

Does any kind human 1) have any idea of what i'm trying to say and 2) know how to actually help me? for some reason i cant find ANYTHING by googling, and no reddit posts as well (may have missed though). even AI cant help even though i prefer not to use it

Hi everyone,

I'm Daniel, a MathWorker who joined the Engineering Development Group (EDG) this past June after graduating in May with a degree in Computer Science and Game Development.

Although it's only been a few months, I'm already working on exciting projects, including some work in the Markdown space for MATLAB. I'd love to hear your thoughts on Markdown and where/how you use it!

Since both my own application process and my first few months at the company are still fresh on my mind, I thought it might be helpful to do an AMA and answer questions about EDG, training and projects, or working at MathWorks in general.

I'm happy to answer whatever questions you all have, from the interview process, to the day-to-day, to my favorite color!

See the attached photo for verification, and as a disclaimer: while I do work for MathWorks, I am not an official spokesperson of the company, and everything I say here is my personal opinion.

I’m trying to learn Matlab. I come from exclusively Python programming. Any books/videos/youtubers you recommend for a beginner?

even after reinstalling matlab, trying out both 2026b and 2025b, this bug is persisting. It doesnt even show up when using ver command (pic 2). Can someone help?

Those results can be easily obtain with simulink

Hey everyone!

I'm a computer engineering student, and MATLAB is something we use quite a lot at university, especially for signal processing, mathematical modeling, and other engineering subjects.

A while ago, I started working on a website with different online tools, and one of the things I wanted to add was a way to quickly run MATLAB-style code without having to install anything.

So I ended up building a browser-based compiler powered by GNU Octave, which is free and open source and supports a lot of MATLAB's syntax and functionality.

Here's the compiler if anyone wants to try it:

https://theonlinetoolset.com/tools/octave-compiler

The idea is to make it easy to experiment with things like:

• Matrices and linear algebra – matrix operations, solving equations, and numerical calculations.
• Mathematical functions – testing formulas and numerical methods.
• Signal processing – experimenting with signals, FFTs, and related calculations where supported.
• Plotting and visualization – working with graphs and mathematical results.
• .m file support – working with MATLAB/Octave scripts and functions.
• Engineering coursework – quickly testing small scripts and calculations.

One thing I seriously underestimated was how complicated it would be to run code submitted by users while keeping everything isolated and managing the server's resources.

It's definitely been an interesting challenge, and I'm still working on improving the experience.

Of course, since it's running GNU Octave rather than MATLAB itself, compatibility isn't perfect. Some MATLAB-specific functions and proprietary toolboxes won't work, and I'm not trying to pretend otherwise.

The goal isn't to replace MATLAB or a full desktop installation. I mainly wanted something convenient for students, teachers, or anyone who just needs to quickly experiment with a piece of code.

I'm actually curious about something:

For those of you who regularly work with MATLAB or Octave, what are the biggest compatibility issues you've encountered between the two?

Are there particular functions, toolboxes, or features you rely on that tend to be missing from Octave?

And if you give my compiler a try, I'd genuinely appreciate hearing about anything that doesn't work properly or could be improved.

I'm still developing the project alongside university, so feedback from people who use MATLAB professionally or academically would be incredibly helpful.

Does anyone knows MATLAB in depth . I need a teammate for this competition. If you wanna teamup DM me .

I am building an EV digital twin in Simulink using the standard Longitudinal Wheel and Vehicle Body 3DOF Longitudinal blocks. I am not using the Simscape Driveline physical hub/axle blocks. The math signals are routed directly (Fx to FwF, and xdot back to Vx).

The Problem:

The vehicle speed (xdot) is stuck at exactly 0. The solver completes the run, but the vehicle refuses to move.

What I have proven so far:

1. The powertrain works: The wheel block successfully outputs 6136 N of forward thrust (Fx).
2. The chassis works: I bypassed the tire model completely and fed a Step block (8000 N) directly into the Vehicle Body's FwF port. The chassis accelerated perfectly on the scope.
3. The zero-speed freeze strictly happens when I close the feedback loop (feeding vehicle speed xdot back into the tire's Vx input).

Attempted Fixes:

I suspect the Magic Formula tire model is hitting a divide-by-zero singularity at $t=0$, causing an algebraic loop. To fix this, I have already tried:

• Setting the solver to ode15s.
• Setting the Vehicle Body Initial velocity to 0.1 m/s.
• Inserting a 1 / (0.01s + 1) Transfer Function on the Vx feedback line.
• Adding a Saturation block (Lower limit 0.1) on the Vx feedback line.

Despite this, the vehicle remains locked at 0 speed. Does anyone know the specific trick to initialize this math loop so the vehicle can pull away from 0?

Discord shows when you're gaming or listening to Spotify, but six hours of debugging a Simulink model shows up as nothing. I'm an electrical engineering student and live in MATLAB most of the week, so I wrote drpc, Discord Rich Presence for MATLAB.

What it shows

• Editing pid_controller.m, with the line you're on and whether it's saved
• Running a script, timed from when the run started
• Debugging, paused at line 87
• Simulating a Simulink model, with % done
• App Designer, figures, the Command Window, and "Away" after 10 minutes idle

How it works

• It runs entirely inside MATLAB. No Python or Node helper in the background.
• A watchdog on a background thread notices when MATLAB is stuck in a long loop and switches you to "Running", so your status doesn't freeze.
• MATLAB never waits on Discord. If Discord is closed or restarting, MATLAB doesn't notice, and drpc reconnects when it comes back.
• The small C# bridge that talks to Discord is compiled on your PC from source, using the compiler that already ships with Windows. The repo contains no DLLs or EXEs.

Privacy: drpc names off hides file names, hidden_folders hides specific projects, and drpc pause hides everything for the session. It only talks to the Discord app on your own PC.

Install: paste this into the Command Window:

unzip("https://github.com/akeanti/matlab-discord-rpc/archive/refs/heads/main.zip", tempdir); run(fullfile(tempdir, "matlab-discord-rpc-main", "install.m"))

If you'd rather read the code first, download the latest release, look through it, and run install yourself.

Limits: Windows 10/11 only for now. You need the Discord desktop app and R2021a or newer. I've tested it on R2024a. On R2025a and later, telling the Editor apart from the Command Window relies on the old desktop, so that one detail may be off. If you're on 2025a+, I'd really like to know how it behaves.

macOS and Linux would need a different bridge (Discord uses a Unix socket there instead of a named pipe). It's doable, and PRs are welcome.

What part of MATLAB should it show that it doesn't yet?

My Korean colleague was watching the new K-Drama Between Steps (Episode 3) and did a double-take when the dialogue suddenly turned to MATLAB and Simulink. Thought you might also appreciate it.

You can watch it on Disney+ or Hulu in the US.

Hello everyone, I hope you're all doing well... Well 😊... I'm using COMSOL 6.2, working on a simulation of a proton-exchange membrane water electrolysis system. The problem is, I'm not very experienced with COMSOL and I need to build the model myself from scratch. I haven't found a model in comsol's library 😭 there is a model for a fuel cell, but that's not what I need. Every time I ask for help on Facebook, I get comments about paid services, and I don't even know if they're legitimate... Any advice?

I’m looking for someone who has experience with MATLAB Simulink regarding propulsion system?

I already have an existing Simulink model, but I’m still learning how to understand, analyse, and work with it.

I’m hoping to find someone who can guide me through the model, and teach me how to make modifications of the parameters.

I’m happy to offer some compensation for your time and guidance.

Online tutoring is perfectly fine!

If you have experience in this area or know someone who does, please feel free to DM me.

Thank you so much!

Hey guys! I'm a recent BTech graduate and I wanted to learn MATLAB as a skill but my college didn't provide me with free access. I was hoping I could share the access with one of you if you have a college provided free access account. I could still use the 1 month trial version but this is just better and cleaner. Let me know if anyone is up to it!

Thanks in advance

I'm using matlab to study an exam for orbital mechanics (setting up Codes that calculate ground tracks predict new orbit after a maneuver, all that jazz)

I've thought of sitting down after the exam and turn them into one Big app that students can use to practice and the department may use for their lessons (i wanted to be able to set up exercises like a target orbit to reach or an object to rendevouz)

However, i'm not familiar with the appdesigner yet, and this i'm a bit confused.

For example, how is data stored inside functions? I wanted to make a script that would let you preview the maneuver effect, them hit "confirm" or "redo" and update current maneuver to the estimated maneuver, for example, and sum the extra deltaV and time of flight into a stored data. How do i keep databases that span múltiple functions? Thanks in advance

Hello, I was wondering if anyone has the same problem or experienced something similar. Recently, the chack boxes and value fields stop showing. They build underneath, the mechanics still work, if I press where the check box use to the action runs, but the box itself doesn't build in the UI.

I am not sure if it is connected to or not but recently I updated to MACOS 27 and that produced seemingly unrelated bugs with other apps.

Hi everyone,

I am an undergraduate student and recently we had a graded project course where we have to work on something that we are interested in. Me and my friend have the basics of matlab knowledge but idk what happened to us we chose to do behavioural modelling of ADPLL for BLE application using MATLAB and simulink.

I can describe my project like this

A MATLAB/Simulink-based behavioral analysis of a BLE ADPLL, with emphasis on transient response, frequency tracking, closed-loop behavior, and the effect of TDC quantization and DCO variations on locking performance.

But now we are stuck. I am really confused about what I am supposed to do and what i am doing. I am not able to understand most of the things and our guide is useless, she is not helping a bit. I know we rushed and stuff but we don't have any options left and we can't back out now.

I just want someone to guide me through the process and genuine opinions on the project and to answer my doubts. Please help me out if you can!

The deadline for this project is 26th so I am kind of in hell.

If anyone has any tips please drop them in the comments!

I’m modeling a 3D compliant hinge mechanism in MATLAB with large rotations. I first used a rotational spring at a single node, but most of the deformation happened in the surrounding beam elements instead of the hinge.

What is the best way to model this type of compliant hinge in MATLAB? Any reference, example, or code would be very helpful.

Hey everyone,

i put together a quick step-by-step GitHub repo on how to properly install and run the Windows version of MATLAB on Linux using Wine.

You can find the short guide here:
