Error when using exportgraphics function to save large vector graphics with transparency
When I tried to save a large vector graphic with transparency information using the exportgraphics function on my PC, an error occurred.
MATLAB version: 9.12.0.2529717 (R2022a) Update 8
Operating system: Microsoft Windows 10 Pro Version 10.0 (Build 19045)
Java version: Java 1.8.0_202-b08 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode
After plotting a large 3D vector graphic with complex perspectives and transparency relationships in a figure, I attempted to run the following code to save the figure:
exportgraphics(gca, ‘picture1.emf’, ‘BackgroundColor’, ‘none’, ‘ContentType’, ‘vector’)
However, the program threw an error.
The error message was:

I tried running MATLAB as an administrator and on a PC with higher memory, but the error persisted, and the error message remained the same. In addition, I checked the available storage space on my computer, and I have at least 390 GB of free space.
When I saved the same figure without transparency information as an image (using exportgraphics(gca, ‘picture1.emf’, ‘BackgroundColor’, ‘none’, ‘ContentType’, ‘image’)), the exportgraphics function worked correctly.
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.

Help with assessing learners work
Hi All,
I am trying to assess students work for a reference solution below, but the problem is that when one thing is wrong, it is marking everything as wrong even though some elements of the learner’s code are correct. For example, say, UTM is correct but RREF is wrong, the assessment will also assess UTM as wrong. Is there a way I can fix this
function [AI UTM RREF INVA] = ROINVERSE(A)
%% Step 1: Matrix Validation
% Establish the Size of the Matrix [m n]
[m n] = size (A) ;
% Check if the Matrix is Square
if m~=n
error(‘Matrix Is Not Square’) ;
% Check Matrix For Singularity
elseif det(A) == 0
error(‘Matrix Is Not Invertible Since |A|=0’) ;
% Inform The User The Matrix Can Be Inverted
else

end
%% Step 2: Augmented Matrix AI
AI = [A eye(m)] ;
%% Step 3: Upper Triangular Matrix UTM
UTM = AI ;
for i = 1:m
% Making All The Pivots = 1
UTM(i,:) = UTM(i,:)./UTM(i,i)
for j = i+1:n
% Making Values Below Pivots Equal to Zero

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?

I am currently working on automating my workflow with Simscape and the HDL Coder. Unfortunately, I cannot find an option to run and configure the Simscape HDL Workflow Advisor (sschdladvisor) from the command line. Is there any way to do this?
Thanks

why i can’t get same plot when i change Real to Im?
i plot the real one but when i change the plot for abs i can get the abs why i can’t get that of this function
0.2e1 * (0.4e1 * exp((-8 * t + 2 * x)) + 0.9e1 * exp((-27 * t + 3 * x)) + 0.25e2 * exp((-35 * t + 5 * x + 2))) / (exp(0.2e1) + exp((-8 * t + 2 * x)) + exp((-27 * t + 3 * x)) + exp((-35 * t + 5 * x + 2))) – 0.2e1 * (0.2e1 * exp((-8 * t + 2 * x)) + 0.3e1 * exp((-27 * t + 3 * x)) + 0.5e1 * exp((-35 * t + 5 * x + 2))) ^ 2 / (exp(0.2e1) + exp((-8 * t + 2 * x)) + exp((-27 * t + 3 * x)) + exp((-35 * t + 5 * x + 2))) ^ 2
