I am new to numpy. I'd like to know if it is possible to code efficient
iterative procedures with numpy. 

Specifically, I have the following problem.

M is an N*N matrix. Q is a N*1 vector. V is an N*1 vector I am trying to
find iteratively from the initial value V_0. The procedure is simply to

(M[i,1]*v_{n+1}[1]+M[I,2]*v_{n+1}[2]+..+M[i,i-1]*v_{n+1}[i-1]) -

I do not see that this is something that can esaily be vectorized, is
