How to save I figure as a image matlab?

Question

I want to save the figure in terms of filename. How can I do this? I use some saveas commands but I couldn't modify it for filename.

imagefilename='lena_gray_256.tif';
maskfilename='M3.tif';
filename = [imagefilename maskfilename];
%Creating plots
imshow(ML)
title('Masked image')

Regards;

I prefer using imwrite :

%//After your code insert
imwrite(frame2im(getframe(gcf)),filename);

The command should recognize the image type by checking the extension. You might want to change the background color of your figure to white before writing the image:

set(gcf,'Color','w')
imwrite(frame2im(getframe(gcf)),filename);

Instead of gcf you can use the function handle of your figure.
