How do I remove the white space from the figures ? I don't want to have to save the image then manually crop it.
Instead of Matlab's dumb figure it would be something like
smart_figure('NoWhiteSpace');
plot(..);
or
figure;
plot(..);
smart_clean('NoWhiteSpace');
Is there such a function ?

Try the new exportgraphics() function.

This problem can be addressed manually in Export setup. Once figures are done File--> Export setup --> Size --> Check expand axes to fill figures.

Thank you, it worked, but I have an additional question: when the axes fills the figure, it breaks the aspect ratio of the content. How can I make sure that the aspect ratio stays the same when filling?

What is in your axes? Line plots? Images? If it's images, use
axis('on', 'image');
to make sure the aspect ratio is correct.

Attach images showing what you have and what you want.
You can change the amount of gray padding about your axes by setting the Position property of the axes.

I find the following really useful:
First, assemble your figure as you normally would. Then, try this:
I0 = getframe;
imwrite(I0.cdata, fullfile(path,'image.png'))
I have the impression that it needs some time for saving, so if used in code where stuff happens after this line it can sometimes give weird results. If you have the figure ready and then execute the code from the command line, it normally works beautifully.
