Sorry for the rapid repost, but I thought of a much easier way to ask the question I asked a few minutes ago.
I have two matrices, A and B, both of which are n x m. n is big (~10,000), and m is small (~10). I want to take the product AB such that I get a length-n vector, as in: >>> AB = zeros(n,'d') >>> for i in xrange(n): >>> AB[i] = dot(A[i,:],B[i,:]) only I don't want the for-loop. The various things I've tried with dot and tensordot inevitably give me a n x n matrix, which isn't what I want. Can anyone help me find an easier way to do this? -- Rick Muller rpmul...@gmail.com
