I am trying to add into my signal 2 quote marks. for example:

signal.wav and I would like to change it likes this: 'signal.wav'

I have done this so far:

a=strcat(signal_data,'.wav'); which gives me a=signal.wav

bear in mind that the signal name is keep chaning as it is in loop.

signal.wav

fun.wav

example.wav

在 MATLAB Online 中打开

Not sure why you would want something like that. Following works

signal_data = 'signal';
a=strcat('''', signal_data,'.wav''');

Result

>> disp(a)
'signal.wav'

@GreyHunter: processing multiple files is a very common task, the basic concepts are shown in the MATLAB documentation (note: no superfluous single quotes stuck onto the filenames):

https://www.mathworks.com/help/matlab/import_export/process-a-sequence-of-files.html

Use the dir method, and of course inside the loop you can use whatever function/s you want to import those files, do whatever processing, and then export to some new files.

I strongly recommend that you keep your code in its own folder (e.g. the MATLAB folder in your Documents directory) and use absolute paths to specify the folders where the files are saved:

You should use this: https://www.mathworks.com/help/matlab/ref/fullfile.html
