Hi everyone. I'd like to save a figure using statements getframe+frame2im+imwrite (without print statement). Is it possible to do it? I wrote the following code:
close all
clear all
t=[0:0.1:10];
x=t;
plot(t,x)
f=getframe(gcf);
[X,Map]=frame2im(f);
a=imwrite(X,'Figura 1.jpg')
but there is the error:
Error using imwrite Too many output arguments.
Error in Untitled2 (line 8) a=imwrite(X,'Figura 1.jpg')
Thank you very much.

imwrite() has no outputs. It just creates the file. If for some reason you want to load the content of the file back in to compare to the data in X that you wrote out, then use imread() on the file.
Note: .jpg files will rarely compare exactly equal to the original data, because JPEG loses information as it compresses data.

Why are you doing all that? If you just want to save your axes as a picture file, use saveas(), or better yet, export_fig().
