dot() and tensordot()

[royG]

hi
can numpy.dot() be used instead of tensordot()? is there any
performance difference? I am talking about operation btw numpy arrays
of dimensions 50 X 20,000 where elements are of float type.

i tried posting in numpy group where i had gotten membership..but when
i post a msg it says posting by non member and so doesn't show up :-(
