How can I save multiple plots to separate image files with variable file name?

Hi, I want to know how I can put the variable file name for saving multiple plots to image files. For example, for 1394x1040 size image, if I create a plot of intensity for every row of pixels and save evey plot to separate image files, I have to use variables in image file name.

Thank you so much for the help.

Plot intensity vs col num (as the row is fixed), clarify?

"...if I create a plot of intensity for every row of pixels and save evey plot to separate image files, I have to use variables in image file name."

Yes, you will have to use variables in the filename. And that is easy with sprintf, something like this:

im = your 1394x1040 image
for k = 1:size(im,1)
    row = im(k,:);
    ... process and plot of each row
    fnm = sprintf('Plot %d.png',k);
    saveas(gcf,fnm)
end

Thank you, Stephen.

Creating filename with sprintf was the answer.
