Hello, I am trying to use a TI C2000 microcontroller to access data from an external adc using I2C. This ADC has multiple channels so I would like to be able to retrive data from all of them. Right now…

Pre 2026a, I had added some custom context menu items using slmenu(cm, ‘Simulink:PreContextMenu’) et.al. Using these methods I was able to exactly determine when a specific menu item was to be shown. e.g. when the selected block had a specific…

I have a list of folder names in that could be in a variety of formats: 368446-SN.24260046-12.08.2026 368446-SN.24260046-12.08.26 368446-SN.24260046.12-08.26 etc. Up until now, the date portion has always been at the end of the name, but that is not guarenteed.…

I am a representative of an organization promoting education, project-based learning, and community service with a focus in engineering, science, math (STEM), etc. How do I request participation or sponsorship from MathWorks on behalf of my social organization?I am a…

Does MATLAB support block iterative linear system solvers for solving multiple right-hand side vectors simultaneously in R2026a? Specifically, for a coefficient matrix "A", a matrix of right-hand side vectors "B", and a solution matrix "X", does MATLAB support solving: A*X…

I installed a specific IVI-C driver on Windows 10 and I’d like to use this in MATLAB to control an instrument connected to my computer. However, I’m not sure where the driver was installed, so I’m not sure how to…

I am building a MEX shared library using MATLAB R2025a and Visual Studio 2022 17.14. The compilation completes successfully, but when I run my validation script, I get a not-a-number (NaN) result, instead of the expected floating-point value (e.g., 17.686). …

I am trying to connect to my Simulink Real-Time Speedgoat target machine across a network or VPN that uses Network Address Translation (NAT). I can ping the target machine and connect to it using SSH and FTP, but I am…

I have some large h5 files that I am unable to efficiently bring into MATLAB. Each group in these large files (50+GB for some) turns into a structure with dozens of fields, each of which is a vector with millions…

I need to calculate the area and mean aerodynamic chord of a modified eliptical wing. The folowing equations describe the leading edge y_le = ((ls/k).^2 – (x*(ls/k)/(b/2)).^2).^(1/2) and trailing edge l_te = (((k-k1)*(ls/k)).^2 – ((k-k1)*x*(ls/k)/(b/2).^2)).^(1/2), where x is the coordinate…

Hi everyone, I am observing unexpected scaling behavior when modeling a 5 kW, 400 V, 50 Hz synchronous machine using the Synchronous Machine Round Rotor block from Simscape Electrical (Fundamental Parameters mode). When attempting to excite the rotor using a…

Hello, I fitted three model parameters to data, and I was able to retrieve the optimization results and get the confidence intervals on both parameters and model predictions, as explained in PredictionConfidenceInterval – Object containing confidence interval results for model…

I have an area arbitrarily divided into contract tracts by FSA (Farm Service Agency) and an artificial waterway. I need to be able find an area to equalize the areas between two of the tracts on either side of the…

I am using a serial port object to control stepper motors like this: sObject_motor = serialport(‘COM3’,115200); sObject_motor.Timeout = 2; sObject_motor.ByteOrder = "little-endian"; configureCallback(sObject_motor,"byte",8,@FAS_serialReadCallbackFunction); There should be always at least 8 bytes sent by the controller as a response to any…

I have a problem in drawing the horizontal pattern using the array factor, because i don’t have the correct equation for the horizontal, which is not the same equation for the vertical pattern , if any one can help me…

Hallo Everyone, I am trying to merge three mat.fig in a single figure as subplots which has multiple axis. But when i run it using the following code all the three figures are overlapping on each other. My code is…

I’m trying to create a Winkel Tripel Earth Map centered at 60°W longitude. It is centered at 60°W but there are horizontal black lines across the map that I would like to avoid or delete. Also, I would like to…

I want to compile an application with compile app (standaloneApplicationCompiler) and deploy a folder with the installed application. My goal is to place that folder in the same　installation directory as the executable, for example:   C:Program Filesxxx   |- appname.exe…

My R2026a Home Edition takes a long time with Mullvad VPN enabled and much less when it is not. Is MATLAB phoning home or something? I have an M3 Mac with 36GB RAM running Sequoia. Timing results below: With VPN:…
