Hi,
I am encountering Invalid Handle Error in saveas command. I am able to display the spectrogram images in for loop, but not able to save them in a specified folder.
fig = specgram(--------------------------------);
cpath = 'c:Users\Desktop\name';
gca = fig;
saveas(gca,fullfile(cpath,filename), 'jpeg');
Thanks in advance

Do not shadow the built-in function "gca".
The first output of specgram is y, not the figure handle. If you want to get the handle, use gcf.
specgram(--------------------------------);
cpath = 'c:Users\Desktop\name';
saveas(gcf, fullfile(cpath,filename), 'jpeg');
