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. __________________________________________________ Do You Yahoo!?
