How can I change the tick marks scale in MATLAB?

Question

Hey,

I have a matrix A which I am plotting using imagesc(A). The matrix is a 512 X 512 matrix, but I need the axes to be labeled from 0 to 4000 instead of 0 to 512. I can't seem to find where I can change this instead of just changing from where to where the points are plotted!

Answer 1

Does this accomplish what you want?:

imagesc([0 4000],[0 4000],A);

Answer 2

I think you should use the XTick, YTick Property.
