Convert matrix to colormap

[alex1604]

Hey!

I'm an imageJ beginner and I was wondering if there is any possibility to convert a matrix to a colormap?
If so, how can I do it?

Thanks in advance,
Alex

I = mat2gray( A , [amin amax] ) converts the matrix A to a grayscale image I that contains values in the range 0 (black) to 1 (white). amin and amax are the values in A that correspond to 0 and 1 in I . Values less than amin are clipped to 0, and values greater than amax are clipped to 1.
