# Fprint.m

2D spectrum integral fingerprinting utility. Breaks the spectrum down into bins of user-specified size and returns the integrals over those bins. Syntax:

                    fp=fprint(spectrum,nbins)


Parameters:

     spectrum    - the matrix of a real or complex 2D spectrum

        nbins    - a vector with two integers, specifying the
number of bins in each spectral dimension


Note: spectrum matrix dimensions must be divisible by the corres- ponding element of nbins vector.
