Accelerate executable file speed

Hello,

I'm new in matlab and also in programming. I have got an assignment from my internship to speed up an exe form of the matlab GUI. The GUI has lots of sub-folder and .m files. Currently it's fast when I run it with matlab, but if I change it to exe with matlab compiler it takes eternity to run. I have seen some solution on the internet to use "MCR_CACHE_ROOT", but no one from university or work knows about it. I have no idea, what it is and how to even start with it. Can anyone please explain it to me like I'm a 5 years old? I would be really grateful.

Thanks

What exactly is "an exe form of the matlab GUI"? What does it mean, that a "GUI has subfolders"? GUIs are the windows on the screen an subfolders are nestes folders on the file system. Please explain, what "takes eternity to run" exactly means. Using the unit seconds is much better that emotional expressions.

As long as it is not clear, where the time is spent, the chances for a matching guess, which solves the problem, are very small.

After I convert the main file(mlapp) and the m files as executable file using compiler, it takes nearly 10-20 minutes for the GUI to start, and response time of each button click is half to one minute or even more. If I run the mlapp file from matlab, the loading time of GUI is less than a minute and button click response time is only few seconds.

Okay, now the problem is clear. Which Matlab version and OS are you using? See:

I'm using R2020b. Now the problem I'm having is

" export MCR_CACHE_ROOT=/tmp/mcr_cache_root_$USER # local to host

mkdir -p @MCR_CACHE_ROOT "

I couldn't find a better explanation for this procedure. I know only what is does, but I don't know how to apply this and where to start.

@Mubin R: I do not understand the meaning of your comment.

The code in your comment must be executed in a Linux shell. Are you working with Linux?

Sorry, I sent you the wrong one. I wanted to post this one

REM set MCR_CACHE_ROOT=%TEMP%

set MCR_CACHE_ROOT="C:\Documents and Settings\Yair\Matlab Cache\"

myExecutable.exe

I figured it out how to use it, but it didn't make the GUI that fast
