How did you generate the variable ExportPath? And why do you need cd in your code?

I had a same error in my windows computer, so place the matlab GUI app in my c drive of my computer and everthing works perfectly, but for macbook i cannot do the same.

You posted the same comment twice, but neither of them actually show the code you're using. You should be using functions like fullfile or filesep. Both me and Steven suspect that you don't.

[Muhammad Aoun Ejaz Qureshi]

my question is related with the path of app file, which according to the software doesnt exists in my macbook, i am not asking about code.

[Rik]

We are asking about your code. Your error suggests you are hardcoding something you should be doing differently.

Answer 1

[Steven Lord]

Did you use fullfile to assemble the ExportPath variable, did you manually concatenate pieces together with slashes inbetween, or did you type the whole path out manually? I would probably use fullfile as it would put the right separators between parts of the file path.

That trailing \ looks suspicious as well.

You need to take the code and convert all \ directory separators in the code into / directory separators, except for some cases involving using system() . [If your code uses dos() or .NET facilities, that part needs to be rewritten anyhow.]

Or you could rewrite the code so that you never explicitly use \ or / as the directory separator at all, and instead use fullfile()

Note that using / to seperate directories is fine in MS Windows, except for use in COMMAND.COM or CMD.EXE or PowerShell . MS Windows uses / internally, not \ -- it is only the command line processing that needs \
