[Numpy-discussion] dot function or dot notation, matrices, arrays?
Sat Dec 19 00:44:44 CST 2009
np.dot(x.flat, x.flat) _is exactly_ "sum of squares"(x.flat). Your
math education appears to have drawn a distinction between "dot
product" and "scalar product," that, when one is talking about
Euclidean vectors, just isn't there: in that context, they are one and
the same thing.
