[Numpy-discussion] vec-operator

Hi,

A matrix operation is that of stacking the columns of a
matrix one under the other to form a single column.
This operation is called "vec" or "cs" (c)olumn (s)tring

Example

A is a m * n matrix

vec(A) = reshape(transpose(A),(m*n,1))

How can I copy the result of vec(A) into the i-th column of another
matrix called B ?

Thanks in advance.
