axis mapping

Hi Matlabers,
I have an intensity profile obtained after fft2 an aperture function. It is in Kx-Ky plane. I need to map both Kx and Ky to x and y so that the intensity profile in x-y plane. The relationship between Kx and x, Ky and y are just Kx=Constant*x and Ky=Constant*y. Same constant. So basically a scaling of axis. But because the intensity profile is a 2048 by 2048 matrix, I don't know how to map the axes.
Can anyone help me please?

You seem to be asking for
x = Kx/Constant;
y = Ky/Constant;
which will work just as written if Kx and Ky are any kind of numerical array and Constant is a scalar.

Sorry - now I see your reference to scaling the axis. By this I presume you mean the color scale, which you can do using CAXIS.
