Do this.
H=zeros(100);
H(:,10:20)=1;
H(:,80:90)=1;
H(46:55,10:90)=1;
imagesc(H); axis image;
It should be the right H.

Or, if you don't want some weird colormap applied by default (like imagesc applies for some reason):
imshow(H, []);
To write H to disk, you can use imwrite() if it's an integer array and you want a standard image format, or use save() if you want to save a floating point image. If you want to save a screenshot of your entire figure/GUI, use export_fig.
