crosscorr2d (MathScript RT Module Function)
Owning Class: spectral analysis
Requires: MathScript RT Module
Syntax
c = crosscorr2d(a)
c = crosscorr2d(a, b)
Legacy Name: xcorr2
Description
Computes the two-dimensional cross-correlation of the inputs. crosscorr2d(a) is equivalent to crosscorr2d(a, a), which computes the autocorrelation of a.
