Speeding up matrix expotentials by using GPU
Hey all:
I am trying to accelerate the speed of calculation of high dimisional matrix expotential by using GPU, but I find that the speed of calculating them on CPU is faster than GPU, and I can’t find where the problem is. The code is:
dev = gpuDevice();
CPU_time = 0;
GPU_time = 0;
for i = 1:10
CPU_matrix = rand(4096, 4096);
GPU_matrix = gpuArray(complex(CPU_matrix));
tic;
Exp_CPU = expm(-1i * CPU_matrix);
CPU_time = CPU_time + toc;
tic;
Exp_GPU = expm(-1i * GPU_matrix);
GPU_time = GPU_time + toc;
end
disp("CPU time:" + string(CPU_time));
disp("GPU time:" + string(GPU_time));
I tested this code using my computer, and its CPU configuration is: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz, RAM 16 GB. Its GPU configuration is: NVIDIA GeForce GTX 1650. The final result is:
CPU time:452.1338
GPU time:915.5892
Why the speed of GPU is slower than CPU?

How to compute response to single node impulse in structural model from modal eigenvectors directly
According to https://www.mathworks.com/matlabcentral/answers/1968759-scaled-mode-shapes-in-modal-analysis-of-a-simulated-system-and-a-wind-turbine-blade?s_tid=ta_ans_results , in a modal analysis, for each mode shape vector, the component with the largest absolute value is scaled to 1, and the rest of the components in the vector are scaled accordingly for ease of visual comparison of the shapes. I have a structural model (femodel(AnalysisType="structuralModal")with displacement vector results u=[u_x, u_y,u_z ] for various frequencies. I would like to compute the amplitudes of all of the frequencies (found in a limited range of course) for a unit impact vector n ( a delta function in time) at any node directly from the components of u and think it is something like just the inner product of n with u at that node were u not arbitrarily normalized, and by that I take the answer to mean there is one scale factor for the entire u for any node. I’d like to do that for two cases: 1) any node/mass element within the volume as if it were struck by a dark matter particle (assuming assumptons of elastic continuum mechanics remain valid) and 2) for any surface node as if it were struck by a BB or similar – I mean the impulse could have normal and traction components. Perhaps this is just what a transient analysis does . I don’t want to perform a transient analysis as found in examples like the tuning fork for every node and go some analysis of the resulting motions to derive what I’m after, just compute the amplitudes of the normal modes.

Appreciate help with satellite MarkSize and MarkerColor … seems ridiculous to have to ask but I can not waste another hour trying.
Hello. Ihave read the help and tried several variations of the below. MarkerSize and MarkerColor are both properties in the satellite funciton (witing the satelliteScenario). I have tries many variations.. ‘MarkerSize’, 10 // MarkerSize=10 // "MarkerColor", "m", etc… One exmaple is below. I keep getting errors that neither MarkerSize nor MarkerColor are recognized parameters. May be missing something dumb, but have spent an absurb amount of time trying to change colors. It does NOT seem like the help can be right (aside – really seems like the error messages and help could be smarted at this point… pretty obvious after 20 tries what I am trying to do). Apreciate any help.

delaunay function on raspberry pi?
Hello all,
I am trying to convert my code so it can run on a raspberry pi. However, part of my code is a map generator which uses the delaunay function to create a triangulation as follows:
(…)
x = x(:);
y = y(:);
z = z(:);
faces = delaunay(x, y);
randomMap = triangulation(faces, x, y, z);
end
Matlab Coder says it cannot convert the delaunay function. Is there any other function I can use to port this? I have already tried using ‘delaunayTriangulation’ or ‘alphashape’ instead, and tried to directly call ‘qhull’, but neither of these work. And since the delaunay function is built-in, I cannot look at the source code to fix this issue either and I do not know enough about the implementation to implement it from scratch.

how to plot contour of 3D variable
HI
I have issue with my data
I have salinity data with dimension (time,Lat,Lon) and I want to plot a filled 3-D contour
I want to plot salinity at specific
timestep 1:13
for example the size of variable
Lat=24*25;
Lon=24*25;
Salinty=744*24*25;
I am getting error becouse the X ,Y and Salinity had different size
I try for loop but it didn’t worke
for i=1:12;
Sal(i,:,:)=Salinity(i,:,:);
figure
contourf(X,Y,Sal(i,:,:);
end
Can someone help?HI

shape has NaN vertices when adding new shapes to the aggregate shape encloses a void; error assigning shape to antenna
I am creating a PCB antenna pattern adding together copper Polygons and rectangles to make the PCB trace pattern. The copper traces short back on themself forming a region with voids in it.
I have used shape.Rectangle() and shape.Polygon() to create the elements and added them together.
When I show the copper it looks right (needs a little cleanup, but OK).
When I show or mesh the antenna it throws a triangulation error.
Adding the last rectangle that closes the shape causes an NaN. This error was NOT happening in another pattern (make a shape, remove a notch from an edge, bridge the notch with a rectangle…).
…
copper = shape.Polygon(‘Vertices’, 0.001*[MinX MinY 0; MinX MaxY 0; MaxX MaxY 0; MaxX MinY 0]);
stem = shape.Rectangle ("Center", 0.001*[StemX MaxY+StemLen/2], ‘Length’, 0.001*StemWid, ‘Width’, 0.001*StemLen);
copper = copper + stem;
… add rectangles till a closed loop is formed. feed point in stem and loading reactance at far end…
…
show(copper); % looks OK other than jagged corners, see below
Ant = customAntenna (‘Shape’, copper, ‘Load’, Load);
show(Ant); % –> error. If commented, mesh(Ant, …) throws similar error (same error, different call back path)
createFeed (Ant, FeedPoint, 1);
