RAND_INT(R,N) returns an n-by-n matrix containing pseudo-random integer values from range R. Function that uses RAND to generate random integers in the specified linear range, as follows:
result = floor(a + (b-a+1).* rand(N)), where specified range is [a b]
----- Please note: There are lots of ways to do this and lots of interesting submissions on FEX which provide similar results (see below).
Function that transforms 1 or 2D data to match a specified linear dynamic range. NORMALIZE_IMAGE(I,R) applies a linear transformation to the dynamic range of I, mapping pixel intensities to new values over the range R.
