I was taking the optimisation self-paced course and I was planning to show the project of that couse under 'guided projects' for my resume.

I was documenting whatever that course taught me as a word file and using its code in my MATLAB. After this I was planning to upload both on my github...

Is this oki? I aint sure. I'm mentioning it as 'guided project' but those courses aren't free for everyone so I dunno can I place this project like this on github ?

I'm a first year student and I have maths as one of my subjects. We have a lab class for maths and I joined my course a little late so I'm a little lost on what's going on. I need to be able to use MatLab fully for my internal assessment so I kinda just need to practice mostly. (And no, I can't use the computer labs at uni outside of lab classes which is once a week for 3 hours). Should I download Octave?

I ported the 1-D TM group of Zanotto's PPML (an RCWA electromagnetic solver) to NumPy with bug-for-bug fidelity yes, including the vacuum impedance hardcoded as 376.730. The writeup covers the MATLAB↔NumPy traps that actually bit: complex auto-promotion that NumPy silently doesn't do, eigenvector gauge freedom across LAPACK builds, mldivide vs solve on singular systems, and an energy-conservation check in the original that can never fire (abs(NaN) > tol is false in MATLAB - try it). Harness, corpus and report: https://github.com/GrednevMSU/ppml-1d-tm-verify

Not a "MATLAB bad" post. The original code is solid and I replicate it bug-for-bug by default. Sharing the trap list for anyone migrating numerical code: round() half-away-from-zero vs numpy's round-half-to-even (inside the nmax series formula, so it changes array lengths), complex auto-promotion that NumPy doesn't do, ' vs .', library functions printing to stdout, and a docstring feature (complex medium index) that turns out to be latently broken. Full findings file, 714-fixture corpus and the verification report: https://github.com/GrednevMSU/mie-scattering-matlab-to-python

I created an open source project that allows you use Chrome/Edge browser's developer console like MATLAB prompt for most common tasks of scientific calculation and plotting: https://github.com/JATLAB/JATLAB.github.io

I hope you guys like it and if you find some functions you want me to add please let me know.

I took a few self-paced courses and I'm on control systems for now. I need to start applying for internships soon is it oki to show whatever I'm learning under 'Projects' in Resume. Although there are some really good project title like 'LTI Modelling a vehicle dynamics' but It feels a little wrong because the whole this is step by step baby fed I will slowly try to make my own projects but is it oki to do it for now, as I think I need to start applying?

The question is about u' that he used he said it is equal u'=u(t)+ulo but this is wrong ,it should be u'=u(t)-ulo ,because if we applied k.v.l it should be u(t)=ulo+ur364+ul364 then take ulo to the next side and we have our u' , maybe my question is simple and no need to ask about it but I am confused and I have exams tomorrow and ai is He hallucinating so excuse me

Thinking of buying the academic perpetual license, but confused on some of the details. Can I use it on multiple computers or just one? If I wanted to update the version, how much would it cost?

This is coming in MATLAB R2026b which will include a completely new object management system that is not turned on by default. When switched on, the new system promises to make object oriented MATLAB code faster without the need to change any code (most of the time). Sometimes, it will be much faster!

More details including release plans can be found over at The MATLAB Blog Objects are about to get much faster in MATLAB » The MATLAB Blog - MATLAB & Simulink

Can we tell with confidence that, in Simulink, PMSM model with back emf waveform set as trapezoidal is same as or atleast be equivalent to BLDC?

Hi r/matlab - I'm the maintainer of MATLAB Simulink Energy Lab, a small open-source collection of energy-system examples designed to be opened, inspected, modified, and questioned.

The current release includes:

- a first-order battery RC model driven by pulse-current data;

- an averaged converter calculation for output voltage, load current, and ripple;

- lightweight no-plot validation checks; and

- explicit parameters, units, assumptions, and limitations.

The examples currently run in base MATLAB. They are deliberately understandable reference implementations, not calibrated production models; native Simulink versions are on the roadmap.

Repository:

https://github.com/mohammadrezwankhan/matlab-simulink-energy-lab

I would especially value technical feedback on three questions:

Which assumption or parameter needs clearer documentation?

What validation plot or dataset would make the examples more useful?

What should come next: temperature-aware battery dynamics, closed-loop converter control, or an averaged-versus-switched comparison?

If the repository is genuinely useful to you, a star helps other MATLAB learners find it. Issues and focused contributions are equally welcome.

Disclosure: This post was drafted with help from ChatGPT/Codex. I maintain the repository and reviewed the technical claims and wording before posting.

I maintain MATLAB Simulink Energy Lab, a small, inspectable energy-system repository, and I would value technical feedback from r/matlab.

What is runnable today:

- A first-order battery RC model driven by pulse-current data

- A CSV input profile and no-plot checks for SOC and terminal-voltage behavior

- An algebraic converter average-model scaffold with parameter checks

- Documentation of assumptions, units, limitations, and contribution paths

The examples use base MATLAB functionality and were verified with MATLAB R2026a.

An important limitation: the current executable assets are .m scripts, and the converter example is an average-model scaffold rather than a switching simulation. Native Simulink implementations are on the roadmap. These are educational references, not calibrated design models.

Repository:

https://github.com/mohammadrezwankhan/matlab-simulink-energy-lab

Two questions for the community:

1. Would the next example be more useful as measured-data battery parameter identification or a switching-versus-average converter comparison?

2. Which validation checks or plots would you expect before considering either model trustworthy enough to extend?

If you find the project genuinely useful, a star helps other energy-system learners discover it. Critical feedback, reproducible issues, and focused pull requests are even more valuable.

Disclosure: I maintain the repository. This post was drafted with AI assistance and reviewed against passing MATLAB checks and the repository's Markdown link check.

Given an integer number i, I want to pass it as an input argument to fi constructor (resulting in x instance of embedded.fi), such that storedInteger(x) = i. In other words, I want to change the interpretation of i to an embedded.fi, just like storedInteger changes the interpretation of the embedded.fi to an integer.

How can I achieve this?

During my physics undergrad, we learnt python, always using NumPy and Matplotlib, as well as SciPy, pandas and sometimes AstroPy too. I wanted to learn MATLAB as it's used for a lot of engineering jobs I've been wanting to apply for, but the basics have so far been extremely similar to, if not the same as, NumPy and Matplotlib. My thought process was to start from the ground up because I thought the syntax would be an issue for me but the difference is so minor that I'm not sure if it's necessary.

So where should I start from as someone who is already very familiar with NumPy and Matplotlib? Also, if there are any engineers who need to use MATLAB for work, are there any specific areas and libraries I should familiarise myself with?

Hey everyone! I've been working on a collection of foundational MATLAB and Simulink models focused on energy systems (specifically battery RC models and converter average models).

A lot of the models out there are either too complex for educational purposes or lack clear validation. I designed these to be highly inspectable, with explicit assumptions and no-plot validation checks built-in.

If you're studying power electronics or battery modeling, I'd love for you to check it out!

If you find it useful, a star on GitHub would be incredibly appreciated! Let me know if you have any feedback or requests for new models.

Technical preview for PHX Toolbox, an object-oriented MATLAB API and Simulink blocks for 3D rigid-body physics, powered by the Bullet physics engine, is out on fileexchange.

Features so far, with more to come:

• Rigid-body dynamics with collisions and contacts (boxes, spheres, cylinders, cones, capsules, meshes, terrain, imported OBJ/STL, …)
• Joints (revolute, spherical, gear, …), springs and ropes
• Force and field elements (thrusters, resistance, dipole/monopole fields)
• Logging, tracing and measurement tools, interactive viewer
• Simulink block for closed-loop co-simulation
• Headless stepping for batch runs and experiments

The toolbox comes with a set of examples and a user manual. It runs on all platforms (Windows, MacOS, Linux), as well as in MATLAB Online. It also includes a set of AI skills for use with common AI agents.

Any evaluation and feedback will be appriciated!

Ciao, sto usando matlab online per studenti universitari per prepararmi ad un esame di automatica, da oggi il comando controlSystemDesigner non mi funziona più e mi restituisce sempre la risposta:

error using controlSystemDesigner

Invalid argument at position 1. Valure must be members of the required set.

Lo restituisce anche se non inserisco parametri

Ciò succede in ogni livescript, anche per quelli a cui avevo già lavorato e quindi non può essere un problema di un singolo live script.

Cosa posso fare? Grazie in anticipo

Lets say I have an array of 2D points. I want to find the nearest other points to each point in the array in sorted order.

So for point 1 it would be [4, 6, 5, 2, 3]. I'd like to do this for all 6 (x,y) points.

sC = [ 28 2597 3803 1417 2127 1888;...

1496 1640 646 2092 1614 888];

Hi all,

I'm a high school student from Washington. I want to use MATLab to conduct my own research for control systems in robotics and UAVs. However, I'm sort of confused on the wording on some of the licenses.

Am I eligible for a student license? It makes it seem like you need to be a University student or otherwise.
