It's in Econometrics Toolbox.

http://www.mathworks.com/help/toolbox/econ/crosscorr.html

while XCORR is in Signal Processing Toolbox.

One difference I see between them at first glance is what they return and
what options they allow. Signal Processing Toolbox just returns the
correlations and lags while allowing the user to specify a normalization
method, while Econometrics Toolbox returns correlations, lags, and
confidence bounds but does not allow the user to specify a normalization
method.
