I attached a screenshot of my plot.
I would like to put on the left (instead of above) the titles (Currents at -70mv, -50, -30 and -10) of the four subplots on the left; on the other hand, I would like to put on the right (instead of above) the titles (Currents at -60mv, -40, -20 and 0) of the four subplots on the right. This is to save space and delete some of the blank space between the subplots.
As for the subtitle ("I is 2 times slower than E"), I’d like to have only one instead of eight, possibly above all the subplots in the centre.
This is how I’m doing now (there’s another for loop "for rat = 1:colnum2" outside here but it’s not relevant for this question):
for vol = 1:colnum
subplot(4,2,vol);
plot(t_plot, currents(:,hh:zz), ‘linewidth’,2); legend(‘IPSC’, ‘EPSC’, ‘CPSC’);
str = sprintf(‘Currents at %d mV ‘, Vm(1,vol));
title(str)
subtitle([‘I is ‘, num2str(ratio(rat)), ‘ times slower than E’])
xlabel(‘Time(msec)’, ‘fontsize’, 7)
ylabel(‘Microamperes (uA)’, ‘fontsize’, 7);
hh = hh + niter;
zz = zz + niter;
end

Hi
I am looking for a fast code to do the following:
get a matrix with elements between 0 and 15
create a new matrix, double the size (both rows and columns)
for each element in the first matrix, set the binary representation of this element in the new matrix, in a 2×2 way.
first example
for a 1×1 input matrix:
A =

7
The result will be:
B =

0 1
1 1

Second example
for a 2×2 input matrix:
A =
0 2
1 3
The result will be:
B =

0 0 0 0
0 0 1 0
0 0 0 0
0 1 1 1
=

Currently, I do this with a slow for loop.
I would greatly apreciate your help.

I am trying to achieve parallel exectution of two functions that would normally need two separate matlab(r2023a) windows open in order to successfuly execute. The PULM() function is a MEX funtion and DMD_Funtion is a matlab function that uses a library (‘alp4395’). because of this, a threadpool does not work because ‘Use of MEX functions is not supported on a thread-based worker.’ The reason either a parallel processing function or 2 MATLAB windows are needed is because PULM() needs to initialize into its ready state then it waits for a trigger (meaning matlab will stay ‘Busy’ and wont execute any other commands until PULM is finished, which waits indefinitely for a trigger), which is the DMD_Function(), then finishes the rest of the PULM MEX functions to collect data and exit.
I have been trying to use parpool(‘Processes’) instead, however it seems that it is unable to successfully ‘exit gracefully’ from the C code, probably due to timing issues with the trigger. PULM() needs several seconds to be in its ‘Ready’ state before the DMD_Funtion() is ran or else the PULM() will be waiting for triggers and basically never exit. I noticed that even with the Pause(5) or even 10 that I put in before the the DMD funtion is ran, all that happens is that both workers wait 5 seconds before running simultaneously instead of being delayed like they are supposed to. How do I delay the exectution of the DMD funtion? is it possible that i = 3 is running before i = 2 causing both of interations to pause before executing? Are there any other ways I could accomplish parallel processing in this way without the use of 2 MATLAB windows?
Initially I thought using 2 push buttons on a GUI would work because I believed that push buttons worked in parallel, but I soon realized they were executed sequentially. So I now have to use parallel toolbox functions so that one push button with execute everything in parallel.
Here’s the code for the parfor:
parfor i=2:3
if i==2

%pause(1);
%DMD_Function(patternNumber,AvergeNumber,SamplingRate,BinningNumber=768/SamplingRate) 768/32
PULM(PonitNumber,NumberofRecording,AvergeNumber);
%disp(‘run 1’);
disp(‘done 1’)

else
pause(5);
DMD_Function(patternNumber,AvergeNumber,SamplingRate,BinningNumber);

disp(‘done 2’)

end

end

Note: ‘done 1’ does not display meaning it does not complete the MEX function but ‘All records were saved to file’ does display which is right before ‘Exit Gracefully’ for the Digitizer.
In a separate code I tried to why the pause was just making them both wait 5 seconds then simultaneously running instead of being delayed. Threadpools seem to do what I want, it executes i==2 and delays i == 3. I am still not sure as to why Processespools doesn’t do the same thing. I even tried to stop the execution of the i==3 line by having it check if i == 2 wrote in a file, but it just ccomes up with an error. this is the reason why I was wondering if i==3 is being executed faster than i==2.
stateFile = ‘state.txt’;
parfor i = 2:3
if i == 2
%pause(5);
disp(‘hi’)

fid = fopen(stateFile, ‘w’);
fwrite(fid, ‘5’, ‘char’);
fclose(fid);
else
pause(5);
if isfile(stateFile)
fid = fopen(stateFile, ‘r’);
state = fread(fid, ‘*char’)’;
fclose(fid);
% Check if the state value matches
if strcmp(state, ‘5’)
disp(‘hello’);
end

How do I delay the exectution of the DMD funtion? is it possible that i = 3 is running before i = 2 causing both of interations to pause before executing? Are there any other ways I could accomplish parallel processing in this way without the use of 2 MATLAB windows?
Initially I thought using 2 push buttons on a GUI would work because I believed that push buttons worked in parallel, but I soon realized they were executed sequentially. So I now have to use parallel toolbox functions so that one push button with execute everything in parallel.
Here’s the code for the parfor:
parfor i=2:3
if i==2

%pause(1);
%DMD_Function(patternNumber,AvergeNumber,SamplingRate,BinningNumber=768/SamplingRate) 768/32
PULM(PonitNumber,NumberofRecording,AvergeNumber);
%disp(‘run 1’);
disp(‘done 1’)

else
pause(5);
DMD_Function(patternNumber,AvergeNumber,SamplingRate,BinningNumber);

disp(‘done 2’)

end

end

Note: ‘done 1’ does not display meaning it does not complete the MEX function but ‘All records were saved to file’ does display which is right before ‘Exit Gracefully’ for the Digitizer.
In a separate code I tried to why the pause was just making them both wait 5 seconds then simultaneously running instead of being delayed. Threadpools seem to do what I want, it executes i==2 and delays i == 3. I am still not sure as to why Processespools doesn’t do the same thing. I even tried to stop the execution of the i==3 line by having it check if i == 2 wrote in a file, but it just ccomes up with an error. this is the reason why I was wondering if i==3 is being executed faster than i==2.
stateFile = ‘state.txt’;
parfor i = 2:3
if i == 2
%pause(5);
disp(‘hi’)

fid = fopen(stateFile, ‘w’);
fwrite(fid, ‘5’, ‘char’);
fclose(fid);
else
pause(5);
if isfile(stateFile)
fid = fopen(stateFile, ‘r’);
state = fread(fid, ‘*char’)’;
fclose(fid);
% Check if the state value matches
if strcmp(state, ‘5’)
disp(‘hello’);
end
end
end

I made a standalone app using matlab app designer. While making package, the default installation folder for package is showing as ProgramFiles or AppData. But I want to run from the local folder only where the app is located in the User PC. Please suggest the way for doing this.I made a standalone app using matlab app designer.
