How to change .fig name when I use savefig

I want to save mat file to fig file

like this

```

I have 00001.mat , 000002.mat ... file

and I want to save file like 00001.fig, 000002.fig

There is my code

mat_file = dir

name = mat_file(3).name %setdata

[filename,fileformat] = strsplit(name,'.')

load(name)

mat2stft

[S,F,T] = stft(a)

h = pcolor(T,F,abs(S))

set(h,'EdgeColor','none');

axis tight off

stft2fig

figname = strcat(filename(1),'.fig')

savefig((figname))

savefig((figname)) is error.. How to fix it!?

"savefig((figname)) is error.. How to fix it!?"

That depends on what the error is. It might be that the location is write protected, or the name is not valid, or all sorts of things can prevent a file from being saved. We don't know what the reason is, because you did not show the error message.

Please show the complete error message. This means all of the red text.
