It seems to me that Wolfram is following yet another path. From
http://mathworld.wolfram.com/Autocorrelation.html and more importantly
http://mathworld.wolfram.com/Cross-Correlation.html, equation (5):
z_mathworld[k] = sum_n conj(a[n]) * v[n+k]
= conj( sum_n a[n] * conj(v[n+k]) )
= conj( z_numpyDocstring[k] )
= conj( z_numpyCode[-k] )
is the conjugate of what the numpy docstring says. So, now we have at least
three definitions to chose from :-)
Cheers,
Bernhard
