I am talking about the 'take' method of numarray.

See here for more info:

http://stsdas.stsci.edu/numarray/Doc/node33.html
If I initialize a matrix 'mymatrix' by zeros((3,3),

type="Float64"), I get a 3*3 matrix of all zeros.

Look:

from numarray import *

mymatrix = zeros((3,3), type="Float64")

mymatrix
array([[ 0., 0., 0.],

[ 0., 0., 0.],

[ 0., 0., 0.]])

I want to change the zeros of only the first column to

1's. In other words, I want to get:

array([[ 1., 0., 0.],

[ 1., 0., 0.],

[ 1., 0., 0.]])

The 'take' method is able to take out the first

column, but I am not sure if there is a good way of

changing all values of the first column to 1's.

Of course, I know that I can achieve my goal pretty

easily with this:

for i in range(3): mymatrix[i,0] = 1.0

I am just wondering if there is an existing numarray

method that elegantly does it for me.
