Hello, I have previously created my MEX file of my code to speed up its implementation speed on GPU. Fortunately, it got faster by 5 times, and hopefully, I want to know if there is way to implement it with higher speed. Here is my code:
function BPmimo2C(Efield) %#codegen

coder.gpu.kernelfun;

image = complex(zeros(17,54,54));
%% creating kaiser window
numT = 16;
numR= 16;
f = 10e9:0.5e9:20e9;
numF = numel(f);
w = ones(numel(f),1);
viq = repmat(w.’, [1,numT*numR]);

c = physconst(‘LightSpeed’);

%% grid points
xf = (-8:0.3:8)*0.01;
yf = (-8:0.3:8)*0.01;
[uf , vf] = meshgrid(xf,yf);
x1f = uf(:);
y1f = vf(:);

%% initialization

ArrRadius = 30;

TX = [ArrRadius.*cosd((360/15)*(0:14))*0.01 0];
TY = [ArrRadius.*sind((360/15)*(0:14))*0.01 0];

K = 2*pi*f/c;

z = 0.36:0.003:0.41;
% z = 0.4;

for dep = 1:numel(z)

%% making the matrix of <transmitter-grid point> distance
XYPos = [TX.’ TY.’ ones(size(TX,2),1)*(z(dep))];
UVPos = [x1f(:), y1f(:), zeros(size(y1f(:),1),1)];
dtXYUV = pdist2( XYPos, UVPos);
dtXYUV2 = zeros(numR,numel(x1f(:)));
expTerm1 = bsxfun(@times,dtXYUV(:)’ , K’);
expT1 = reshape(expTerm1,[numel(K),numel(TX),numel(x1f)]);
expT2 = zeros(numel(K),numR,numel(x1f),numel(TX));

for i = 1:numel(TX)
expT2(:,:,:,i) = repmat(expT1(:,i,:),[1 numR 1]);
dtXYUV2(:,:,i) = repmat(dtXYUV(i,:),[numR,1]);

end
expT = permute(reshape(permute(expT2,[1 3 2 4]),[numel(K),numel(x1f),numR*numel(TX)]),[1 3 2]);

%% making the matrix of <reciever-grid point> distance
XYPos = [real(Efield(1:numR,2,1)) , real(Efield(1:numR,3,1)), ones(numR,1)*(z(dep))];
UVPos = [x1f(:), y1f(:), zeros(size(y1f(:),1),1)];
dXYUV = pdist2( XYPos, UVPos);
expTerm1 = bsxfun(@times,dXYUV(:)’ , K’);
expR = repmat(reshape(expTerm1,[numel(K),numR,numel(x1f)]),[1 numel(TX) 1]);

%% making the exponentail term
EXP = exp(1i*(expT + expR));

EXP2 = reshape(EXP,[numel(K)*numel(TX)*numR,numel(x1f)]);
Efield2 = reshape(permute(Efield(1:numT*numR,:,:),[3 1 2]),[numel(f)*numT*numR,6]);

image2 = reshape(((viq.’).*Efield2(:,6)).’*EXP2,[sqrt(numel(x1f)),sqrt(numel(x1f))]);

%% gahter to change matrix from GPU-array to normal array
image(dep,:,:) = image2;

end

image = abs(image);

uf = repmat(reshape(uf,[1,numel(xf),numel(yf)]),[numel(z) 1 1]);
vf = repmat(reshape(vf,[1,numel(xf),numel(yf)]),[numel(z) 1 1]);
hf = uf;

for j = 1:numel(z)
hf(j,:,:) = z(j);
end

figure(1);
er = squeeze((image(13,:,:)));
h = surf(squeeze(uf(1,:,:)),squeeze(vf(1,:,:)),er);
colormap(jet);
set(h,’LineStyle’,’none’);
view(2);

end

In addition to speed, sometimes it encounters with "out of memory" error, which is due to huge size of some arrays. I can implement it using multiple nested "for"loops, however, I understood it’d be faster on CPU if I use MATLAB’s matrix multipication capability; Therefore, I preferred matrix-based code rather than multiple nested "for" loops.

Any advice, whether it would be general or specific, would be appreciated.

I need to add 2 toolboxes to Matlab, when I use the "add path" function it adds itself naturally and I "save" the current paths but the problem is once I log off Matlab it restores to the paths before adding these two toolboxes !!

Meanwhile if I said I will add them each time, I have no problem with that but it returns a message calling "out of memory" when trying to use the "sift" command.

I have a Sudoku app with text boxes (numerical, but it doesn’t seem to matter).
I want to control the user input with a ValueChanging callback. These callbacks are working once there’s already a value in them, but the callbacks aren’t called as the value changes from " " to "5555". I tried using a while loop to make them constantly observe the value of the box, but again it only works if the initial value isn’t an empty string…
I don’t know much about events, so if there is a way to force the active textbox to call the ValueChanging callback everytime a key is pressed, I think that is a workable solution.
Here is the callback code as it stands now:
function R11ValueChanging(app, event)
changingValue = event.Value;
while (changingValue ~= "" && changingValue ~= "1" && changingValue ~= "2" && changingValue ~= "3" && changingValue ~= "4" …
&& changingValue ~= "5" && changingValue ~= "6" && changingValue ~= "7" && changingValue ~= "8" && changingValue ~= "9")
app.R11.Value = "";
changingValue = "";
end
end

As I mentioned before, this code does dynamically clear the textbox if something invalid is typed, so in that sense it works, but it just doesn’t seem to recognize the ValueChanging event is occurring when the value begins as an empty string.
Edit: I just double-checked something I said, and I found out something weirder. The callback function is actually called. In debug mode, the invalid character gets deleted. But when I don’t have any breakpoints, the invalid character stays there…. so now I definitely need help with this…

Hello everyone,
i´m having a Simulink Model which consists of custom library blocks. The connections between the blocks can be seen in the attached picture (BlockDiagramm.jpg ; highlighted trace).
During connecting the blocks, the Matlab Command Window gets filled with a lot of warning messages from same type:
"Warning: Trace to source might be incomplete because the trace enters a loop at output port 1 of …"
When I run the model, no warning or error message appears (-> Simulink is able to solve it and serves correct values).
So i´m wondering about the behaviour during building the model – why does Matlab send those warning messages before running the model and how to get rid of them? For signals in a loop I use the "Unit Delay"-Block.

Typing >> Simulink.BlockDiagram.getAlgebraicLoops(bdroot) << provides:
No algebraic loops were found.
ans =
0×0 AlgebraicLoop array with properties:
Model
Id
VariableBlockHandles
BlockHandles
IsArtificial
Typing >> w = warning(‘query’,’last’) << provides:
identifier: ‘Simulink:HiliteTool:LineTracingBusLoopWarning’
state: ‘on’

I know that i can turn the warning off using warning(‘off’,w.identifier) – but it would be nice to debug my model. And if there is not a problem with the model in general, I´d like to disable this warning constantly. It has to be said, that the warning does not appear on the diagnostic screen in Simulink, but in the Command Window in Matlab. Turning off "Edit-Time Errors and Warnings" in Simulink doesn´t help.

I know that i can turn the warning off using warning(‘off’,w.identifier) – but it would be nice to debug my model. And if there is not a problem with the model in general, I´d like to disable this warning constantly. It has to be said, that the warning does not appear on the diagnostic screen in Simulink, but in the Command Window in Matlab. Turning off "Edit-Time Errors and Warnings" in Simulink doesn´t help.
Thanks for your answers in advance. Hello everyone,
i´m having a Simulink Model which consists of custom library blocks. The connections between the blocks can be seen in the attached picture (BlockDiagramm.jpg ; highlighted trace).
During connecting the blocks, the Matlab Command Window gets filled with a lot of warning messages from same type:
"Warning: Trace to source might be incomplete because the trace enters a loop at output port 1 of …"
When I run the model, no warning or error message appears (-> Simulink is able to solve it and serves correct values).
So i´m wondering about the behaviour during building the model – why does Matlab send those warning messages before running the model and how to get rid of them? For signals in a loop I use the "Unit Delay"-Block.

Typing >> Simulink.BlockDiagram.getAlgebraicLoops(bdroot) << provides:
No algebraic loops were found.
ans =
0×0 AlgebraicLoop array with properties:

Typing >> w = warning(‘query’,’last’) << provides:
identifier: ‘Simulink:HiliteTool:LineTracingBusLoopWarning’

Has anyone else had issues with the functionality of ginput with app designer created figures? On seemingly random occasions when ginput is called, the "mouse" pointer predictabily dissappears, but the crosshairs do not appear, leaving the user blind as to where they are on the figure. When this occurs, there appears to be no way to correct it other than to restart the application and losing all progress. The inputs DO still register when the user clicks on the figure though! There are also no errors when the callback is run and the line function run after with these inputs (shown below) will plot on the axes.
I have tried setting the handle visibility to ‘callback’ and specifying the current figure to try to "point" the function to the app figure, but this hasn’t prevented the issue.
For additional context, what I am doing is receiving user input of a range of X values on a 1D plot or 2D matrix, plotted on an app.UIAxes, and store the info in a cell array. The user must cycle through multiple plots/matrices and the app updates the values as they are changed. "r" is the index of the plot they are on, and "e" is the index of the selected input range. The user can add multiple "e"s (input ranges) through an add tool which also utilizes the ginput function.
I have used ginput in a number of ways to collect input on matrices/images as well, and frequently encounter this issue. I’m aware there is a separate selection tool on the axes object however I don’t know how to use it accordingly to programmatically recieve the values in a callback.

function EditPointsButtonPushed(app, event)
r = app.r;
e = app.e
assert(~verLessThan(‘Matlab’, ‘9.9’), ‘ginput not supported prior to Matlab r2020b.’)
fhv = app.UIFigure.HandleVisibility
app.UIFigure.HandleVisibility = ‘callback’
set(0, ‘CurrentFigure’, app.UIFigure)
[X1 ~] = ginput(2)
app.UIFigure.HandleVisibility = fhv;
line([X1(1) X1(1)],[Ymin max(app.Eventplots{r,e}(:,2))]); %1 needs to be axis min
line([X1(2) X1(2)],[Ymin max(app.Eventplots{r,e}(:,2))]);
app.Editpoints = round(X1)
end

I should also mention that the app is structured with a gridlayout, with panels that contain the axes. I thought that possibly ginput was occasionally being called onto the figure underneath these panels, however as others have mentioned in other questions, you cannot specify ginput onto objects/axes/etc and I cannot see the cursor when I move it between panels. I’m not sure what else to try, so any ideas would be greatly appreciated!!Has anyone else had issues with the functionality of ginput with app designer created figures?
