How to reduce the borders around subplots in matlab? [duplicate]

Question

In matlab, an inordinate amount of space is wasted around subplots. For example, in this example:

t = 0:0.001:2*pi+0.001; figure(2); for i = 1 : 25;     subplot(5,5,i);     plot(t, sin(i*t));     axis off end 

over 50% of the space on the figure is wasted as "blank" I'd like to shrink that blank space down, but have been unsuccessful to identify a mechanism to do so. Thoughts?

Answer 1

The subaxis function on the File Exchange allows you to specify margins for subplots.

Example usage:

t = 0:0.001:2*pi+0.001; figure(2); for i = 1 : 25;     subaxis(5,5,i, 'Spacing', 0.03, 'Padding', 0, 'Margin', 0);     plot(t, sin(i*t));     axis tight     axis off end 

Answer 2

You can position them yourself (or programatically) using

subplot('Position',[left bottom width height]); 

By default, the coordinates are normalized. So a position of [0.1 0.1 0.5 0.5] will start at 10% of the way in from the lower left corner, and will have a width equal to half the figure width, and a height equal to half the figure height.

See the accepted answer for a built-in solution to margins and padding.
