Error using build after clibgen.generateLibraryDefinition runs as expected.
I’m attempting to follow a tutorial for interfacing with C++ libraries in MATLAB. The only major difference between my situation and the author’s is that I’m working on a windows machine, meaning that I run
> cl /c rectangle.cpp
> log /OUT:rectangle.lib rectangle.obj
to compile into a .obj file (rather than .o) and reformat it to .lib. Then, in the MATLAB environment, I run
>> headerFile = "C:pathtorectangle.h";
>> libFile = "C:pathtorectangle.lib";
>> libName = "rectangle";
>> clibgen.generateLibraryDefinition(headerFile, "Libraries", libFile, "PackageName", libName)
This runs without issue. The generated definerectangle.m looks as I expect, and the summary looks as follows:
>> summary(definerectangle)

which seems right. However, when I attempt to build, I get the following result

Using drawpoint in 3d axes
Hello,
I have a program that plots the electrostatic potential created by electrons confined to a sphere. What I’d like to be able to do is grab one of those electrons and move it in the figure to see how the potential changes. What I’ve been able to do is project everything from the surface of the sphere onto 2D axes and use drawpoint to get the interactivity I want. However, I’m a little annoyed by the distortions inherent in the projection so before I go and add a bunch of other functionality I have in mind I want to see if I can get the interactivity while having everything remain on the sphere.
One strange thing is that while drawpoint will still create a Point object in 3D axes (constrained to z=0), it’s motion is distorted: upon clicking the point, it jumps away and will move as if constrained to a line parallel to the x- or y-axes. Once the cursor gets far enough away, however, its motion does follow the cursor, just with a constant offset. The magnitude of that offset is a function of the viewing angle: when looking straight down or up the point moves as expected, but a low angle makes the point get very confused.
The fact that the point is always on the xy-plane isn’t necessarily a deal-breaker, though I can already think of several issues. The bigger issue is of course the strange distorted motion. I assume there’s nothing I can really do to fix that, so my question is whether there might be a different way to achieve the same end – some sort of callback on a scatterplot that would update the coordinates based on the mouse position?
If not, I do have an idea for a compromise, but I figured this was interesting enough to ask.

Unable to see uifigure object properties
Hi,
I’m very new to Matlab, I’m basically learning as I go. At the moment I’m working on getting a callback function for a group of two radio buttons to work. The aim of the buttons is to switch between a line graph and a bar graph. The buttons are created fine, and open in the figure but I can’t see the properties.
My script:
chartSwitchGroup = uibuttongroup(tab, ‘Position’, [30, screenSize(4) – 330, 1220, 40],’BorderType’,’none’);
rbLine = uiradiobutton(chartSwitchGroup, ‘Text’, ‘Line Graph’, ‘Position’, [10, 5, 105, 30], ‘Value’, true, ‘FontSize’,16);
rbBar = uiradiobutton(chartSwitchGroup, ‘Text’, ‘Bar Chart’, ‘Position’, [115, 5, 125, 30], ‘FontSize’,16);
rbBar
rbLine
Command window:
I’m just trying to see the properties, basically so I can see what they are and learn more but even when leaving the figure open, I still get the ‘no longer exists message’

Deriving flux and current from the manufacturers B-H curve for inputing values in saturable transformer
Hi,
I was simulating a saturable transformer. It is shown in the figure for hysteresis design tool that the curve is between flux and current. This is a bit confusing. Should we derive the flux and current values from the manufacturers B-H curve and transformer dimensions.

How to output text to Command Window if signal changes from 0 to 1 in Simulink
I want to output text to the command line in Simulink when a signal turns from 0 to 1.
For example, in my model, signal A is zero unless a condition is exceeded in the model, to where signal A is then turned to one. At that point, I want to write "Signal A is 1. Data is invalid" to the command window. I’m currently trying to use a MATLAB function block:
function a = fcn (u)
if u == 1
disp(‘Signal A is 1. Data is invalid’)
a = 1;

Custom Toolbox Documentation for Nested Namespaces
I am trying to create a custom toolbox which has multiple, sometimes nested, namespaces. How do I structure my *.mlx help files such that they appear for all functions within the toolbox.
For example, say my toolbox has the form:

I have one set of 3D images Dicom. below is one of the slices.

Repeated-measures ANOVA with no between-factor
Hi all!
I am trying to perform a two-way repeated measures ANOVA by using the function fitrm and ranova. I have two within-factors (e.g. Condition & Side) and no between-subject factors. I tried the code below, based on the different topics on the mathworks help page. Cause I have no between-subjects factor I thought i should use ~1 as constant. However, I keep getting the following error:

Error when using exportgraphics function to save large vector graphics with transparency

Furthermore, I plotted a smaller image and tried again to save it using exportgraphics(gca, ‘picture1.emf’, ‘BackgroundColor’, ‘none’, ‘ContentType’, ‘vector’), and the result was correct.

How plot density of function ?
i search for finding i have a function which i saw the density plot i want plot the same i need density plot like the picture
for this function

How do I disable the (new) simulink zoom overview?
The bottom left corner of our simulink window is now occupied by this new overlay while zooming/panning around.
I wish to disable this as the overlay is more annoying than helpful to me.

Use WLTC drive cycle data instead of step input
I’m currently working with the PMSM thermal model. I replaced the input speed (RPM) with custom WLTC speed data, specifically the first 50 points of the WLTC profile. I adjusted the simulation time to 50 seconds accordingly. I also interpolated my data to have a time interval of 0.01 seconds, and I verified the input RPM values using a plot—everything appears normal.
However, I encountered the following issues:
Torque Not Measured: In the simulation results , the demanded and achieved torques are not being measured.
Temperature Explosion: After around 10 seconds into the simulation, the motor temperature exhibits an unexpected and unrealistic spike or explosion.
I’ve carefully checked the input RPM data, and everything seems fine. What could be causing these issues? How can I resolve the torque measurement issue and fix the temperature explosion problem?
Any help or suggestions would be greatly appreciated!I’m currently working with the PMSM thermal model.

Reconstructing signal using the IFFT
Hello, I am using the FFt to convert a time series signal into images by reshaping the matrix (N*N). But i am having hard time to get the original signal back from the images. IS it because in fft i am considering only the magnitude of the signal not the phase of the signal ? Is there any way to solve this proble.
