The program takes the columns of an input matrix and calculates the auto and cross correlation of these columns using an fft method. The result is very similar to the xcorr function. This method could be used to evaluate the cross correlation of repeating code sequences, and other similar investigations.

An n x m matrix in will result in an n x m^2 matrix out.

There is a waitbar included to remove the mystery of how long the calculation will take.
