Invalid handle Error in Saveas command

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');
