XCORR2x.m

Normalizes the output of cross-correlation function XCORR2.M according to 'biasflag'.

function C = XCORR2x(A,B,'biasflag')

PURPOSE: Normalizes the output of cross-correlation function XCORR2.M according to 'biasflag':

biased - scales the raw cross-correlation by the maximum number of elements of A and B involved in the generation of any element of C
unbiased - scales the raw correlation by dividing each element in the cross-correlation matrix by the number of products A and B used to generate that element
coeff - normalizes the sequence so that the largest cross-correlation element is identically 1.0.
none - no scaling (this is the default).
