I’m getting an error running the Control Systems Modeling Essentials due to not having Simscape. I didn’t see this listed as a requirement for the course before purchasing Matlab Academy. Is this intentional, or a technical issue with my account?I’m…

I do low-pass filtering on the received data from the X310, and find this step will slow down the processing speed. Can implement filtering in the parallel way? Can I do other demodulation steps parallelly in Matlab? Thanks, AlfredI do…

Generally speaking, I have found that it has always been possible to mix subscript and linear array indexing with any n-dimensional array, as long as it is in the form, A(subscript_1,subscript_2,…,subscript_n, linear_index). For example, given, A = reshape((1:24)*3, [4, 3,…

I just downloaded MATLAB 2025a and all is working well so far except a strange quirk: There is no easy way to close a figure window using standard Mac keyboard shortcuts. In previous versions, I can close a figure window…

Hi, I am designing a push-pull converter. I copied the control from this example after having tried the control that was in another example made by a user. However, that one wasn’t giving a correct closed-loop answer as it was…

I get an output file looking like the following picture when trying to export my triangulation object as an stl. the yellow represents valid faces and the red corresponds to missing faces. The section of code where I generate the…

I’m currently attempting to test a digital filter in simulink, but I do not know how to import my test audio into Simulink. I recorded a .wav file on my computer and I need a way to add it to…

Can you help me? I have a bunch of 2D histograms that I’d like to sharpen so that I can identify some features. Here is an example image: Each vertical line in the image is a scan (row) in my…

Dear all, I use griddata to interpolate one 2D data. The codes worked quite well half a year. But since today, it always showed an error "Error using scatteredInterpolant. Sample values must be a double array." Can anyone do me…

When I want to open a file from my computer (I want to open a matlab file) I get the following error: Exception in thread "AWT-EventQueue-0": com.mathworks.util.event.EventListenerInvocationException: Error firing event: caused by: java.util.MissingResourceException: Can’t find bundle for base name SLDD:sldd,…

I try to run the example. The second line of code workerToClient = parallel.pool.PollableDataQueue(Destination="any") gives me this error: Error using parallel.pool.PollableDataQueue (line 28) Too many input arguments. I remove the Destination = "any" argument and that seems to get things…

We are working on a finite elements model using the plug-in STABIL. We get no errors but our displacements are all giving NaN as solution. Can someone explain the meaning of these NaNs? Our K and P matrix look logical…

I have tried to use an ouptut argument to make a variable and use that variable in my main script, however when it is returning the value I want, it still isnt breaking the while loop? Code for the function:…

Hi all, I understand that ‘symmetric’ in ifft2 assumes data is conjugate symmetric and will output real values, but I want to know how exactly is this done. Specifically: with ‘symmetric’, will only half of the data be used or…

Hello team, I am using the Simscape battery toolbox to estimate ECM Parameters from HPPC test data following the similar example provided. When I load my hppc data, and run hppcTest, I get the error Arrays have incompatible sizes for…

Sample data s.th = pi/4:pi/4:2*pi; s.r = [19 6 12 18 16 11 15 15]; s(2) = s(1); s(2).th = s(2).th*1.3; If I want to make two plots in a tiled layout with Axes I can do this figure t…

Hi everyone, I’m trying to run a test with R-513a, which doesn’t currently exist on the 2P fluid properties block, however, the two fluids which it is a mixture of R-1234yf and R-134a do. Is there a way to leverage…

I would like to use MATLAB to work with and visualize HEALPix data (described in the HEALPix landing page). Does MATLAB have any functions that can handle such data?I would like to use MATLAB to work with and visualize HEALPix data (described in…

Hello all, new MatLab user here, find the tutorials and documentation very useful so far! I am trying to evaluate the performance of a freezer in my lab. I wish to know the rate at which it cools back down…
