Why is it showing “Incorrect” for a Task in “Create Animated Plots with MATLAB” course?
I was doing this task in the new "Create Animated Plots with MATLAB" course. But whenever I ran the code, it showed Incorrect. On closer inspection, I saw that when I ran it manually, the animation ran till x = 7.1 but when the code is executed on clicking "Submit", the animation runs till x is a little less than 7. Why is this happening and how can I complete this task?
Code:
for idx = 1:numel(y)
scatter(x(idx),y(idx),40,’filled’)
drawnow
end

Create random points in a rectangular domain, but with minimum separation distance
Hello,
I am not a regular user of this program. Hence this query.
I am interested to create random points in a 2D rectangular space, to start with, a uniform distribution. I know how to do this. However, I want to ensure that each of these points are separated by a certain minimum distance.
Can anyone help me with the script please.
Thank you.

Is there a way to insert a common ylabel to secondary axes in a tiled layout?
Hi everyone,
Dabbling a bit in MATLAB for the past year, mostly for data analysis. I am currently using version 2020 a and recently started enjoying the tiledlayout functionality. I was wondering, if there is a way to insert a shared y-axis title for secondary y-axes? For example, in this code:
t = tiledlayout(2,2);
for i = 1:4
f = figure(1);
ax = nexttile;
yyaxis left
x = (1:10);
y = rand(1,10)*100;
plot(x,y)
yyaxis right
plot(x,sin(y))
end
xlabel(t,’X’)
ylabel(t,’Y’)
I would like to insert a ylabel for the right axes (lets say ‘Y2’) that is ‘shared’ just as ‘Y’ is for the left axes. I haven’t found a solution that worked for me yet, all information I could find would either relate to tiled layouts or two y axes, I haven’t found something that combines the two.
I hope you understand my problem, any help is highly appreciated.Hi everyone,

F28379D: Cannot clear ePWM Trip Zone flags (TZFLG/TZOSTFLG) using Register Read/Write block in Simulink
Hi everyone,
I am having trouble clearing the Trip Zone flags for ePWM1 on a TMS320F28379D using the Register Read/Write blocks in Simulink.
System Configuration:
Hardware: TMS320F28379D (CPU1).
Software: MATLAB/Simulink (Embedded Coder).
Logic: I have two Register Read/Write blocks configured for Write operation:
Target: EPwm1Regs.TZCLR, bit field: OST.
Target: EPwm1Regs.TZOSTCLR, bit field: OST1.
Input: A uint16 constant of 1 is fed into both blocks.
The Issue:I am monitoring EPwm1Regs.TZFLG and EPwm1Regs.TZOSTFLG using a Scope. Even when the clear command is triggered, these flags stay at 1 and never transition to 0.
Confirmed details:
ISR Execution: The blocks are placed inside an ISR. I’ve verified the ISR is running correctly using a counter variable that increments as expected.
Register Behavior: I am aware that TZCLR and TZOSTCLR are "Write-1-to-Clear" (Self-clearing) and will read back as 0 on the Scope immediately after the write. However, the actual status flags (TZFLG) should return to 0 if the clear was successful, which is not happening here.
Access Mode: Using Specified bits mode for register access.
What could be preventing the TZFLG from clearing?

Register Behavior: I am aware that TZCLR and TZOSTCLR are "Write-1-to-Clear" (Self-clearing) and will read back as 0 on the Scope immediately after the write. However, the actual status flags (TZFLG) should return to 0 if the clear was successful, which is not happening here.
Access Mode: Using Specified bits mode for register access.
What could be preventing the TZFLG from clearing?
Thanks Hi everyone,
I am having trouble clearing the Trip Zone flags for ePWM1 on a TMS320F28379D using the Register Read/Write blocks in Simulink.
System Configuration:
Hardware: TMS320F28379D (CPU1).
Software: MATLAB/Simulink (Embedded Coder).
Logic: I have two Register Read/Write blocks configured for Write operation:
Target: EPwm1Regs.TZCLR, bit field: OST.
Target: EPwm1Regs.TZOSTCLR, bit field: OST1.
Input: A uint16 constant of 1 is fed into both blocks.
The Issue:I am monitoring EPwm1Regs.TZFLG and EPwm1Regs.TZOSTFLG using a Scope. Even when the clear command is triggered, these flags stay at 1 and never transition to 0.

Visualizing Satellite Skyplot Drawnow and Group Inconsistency.
I am developing a script that shows a sky plot of some satellites over a ground station. I am using drawnow and a for loop to make a video visualization of how the satellites az and el change with time. When satellites go below 0 degrees in azimuth, I want to change their color (I am using categorical groups for this). My script shows up differently if I run it in different ways. For instance, when I run it using a Live Script, the visualization only shows antenna positions moving when they all become part of the In View category, meaning there is a pause in movement before and after they all have elevations above 0 degrees. If I run the loop in the command line, the satellites move the entire time like they should BUT they do not retain their colors for their groups. Finally, if I run the Live Script, but pause execution and step through each iteration in the for loop, it works perfectly as intended, all satellites move continuously and the group colors are present. How can it be correct when parsing throught the for loop, but not correct when the full code is run?
<—This is from iterating line by line (it works!)
<— These two frames are from running the Live Editor all the way through, these are updates directly after one another. You can see that the satellite furthest to the right did not update its position fluidly, it just jumped to its actual position when the 3rd satellite came into the picture. And immediately when the 3rd is in view, all of the satellites move and the colors change instead of changing color one by one.
Here is the code.
[az, el, r, timeOut] = aer(gs(1), sat); % finds azimuth, elevation, range, and time between satellites and one
% ground station
skyplotHandle = skyplot(0, 0); % create skyplot for drawing
numSimSteps = (duration * 60 * 60) / sampleTime + 1; % steps in satellite scenario
for i = 1:numSimSteps
% here el(:,i) is a column vector with elevation angles of all satellites at time i
isOutOfView = false(size(el(:,i))); % assume everyone is in view
outOfViewIndex = find(el(:,i) < 0); % find elevation under 0 bc throws error in skyplot
el(outOfViewIndex,i) = 0; % set any elevations below 0 to 0
isOutOfView(outOfViewIndex) = true; % set boolean array to reflect out of view satellites
group = categorical(isOutOfView, [false true], ["Within View" "Outside View"]); % group together
ranges = string(round(r(:,i).*1e-3)); % convert to km, round for display, and define as string vector
ranges = append(ranges, " km"); % append for labeling
% set the data on the sky plot
set(skyplotHandle, ‘AzimuthData’, az(:,i), ‘ElevationData’, el(:,i), ‘LabelData’, ranges, GroupData=group);

How does Matlab interact with custom Diffusion models?
Matlab has been developing the DL Toolbox for many years, and I want to know what it can do now. I know there are already many official examples, but their overall cognitive effect is limited or even outdated.
For example, I want to start LDF-VFI now, which is a Diffusion model, but there are not many related examples. What extent can Matlab achieve this? By calling PyTorch through Matlab to reduce meaningless dependencies; by calling the converted ONNX through Matlab to break away from Python; even optimizing this scheme to reduce actual VRAM and other resource overheads?
If you could provide the specific code flow, I would greatly appreciate it.Matlab has been developing the DL Toolbox for many years, and I want to know what it can do now. I know there are already many official examples, but their overall cognitive effect is limited or even outdated.

Any way to control Matlab window focus?
I’ve seen questions asked related to figures explicitly, but not more generally.
I don’t know when it changed, I’ve just suffered with it from then until now (and probably for future too), but is there anything I can do to stop other bits of Matlab constantly taking focus away from the command window?
I’ve worked in basically the same way for 20 years in Matlab – I have code in files, sometimes it opens figures, sometimes I have the variable editor open, often it will hit a breakpoint where I want to investigate something.
99% if the time what I next want to do is type something in the command window – e.g. I put my breakpoint in because I want to investigate what is happening there, or I opened a figure and now want to set an axes property on it from command line or whatever, I always want to be typing in command window in these situations.
For many years this worked exactly as I want it to, which I guess is why that became my habit. But in more recent versions of Matlab focus is more and more beings stolen by other things:
I create a uifigure, the uifigure window has focus, so my typing achieves nothing
I hit a breakpoint and focus is on the editor window of the file with the breakpoint so now half the time I start typing the code I want to test on command window into my running file and have to undo it. This is never the behaviour I want.
Also recently I’ve been working with the variable editor open and now that steals focus on a breakpoint often too so now when I start typing it replaces some arbitrary cell of my array with text.
Is there really no way I can turn this awful behaviour off and just have it keep focus on the Command window unless I explicitly click on something else (or whatever it was it used to do, that was so intuitive to work with – I never really pinned down exactly what it did because it just worked in a common sense way)?I’ve seen questions asked related to figures explicitly, but not more generally.
