n-dimensional cross-correlation. Generalized version of xcorr2. For 2 dimensional inputs this function is exactly the same as xcorr2, but also works in higher dimensions. It can also be more efficient because it performs convolution in either the spatial or frequency domain. The order of parameters is reversed from normxcorrn. This is to be compatible with the matlab functions normxcorr2 anc xcorr2 which take parameters in different orders. For more information see help on xcorr2.m. For example usage see normxcorrn. INPUTS A - first d-dimensional matrix T - second d-dimensional matrix shape - [optional] 'valid', 'full', or 'same', see convn_fast help OUTPUTS C - correlation matrix DATESTAMP 29-Sep-2005 2:00pm See also XCORR2, NORMXCORRN, XEUCN
