If I have a large matrix, say
a = zeros( (20,20) )
and a small matrix
b = ones( 3,4 )
and a list of row indices and a list of col indices
rind = [2,4,9,15] cind = [1,4,12]
what is the best way to assign the submatrix to a[rind,cind]. I understand this is possible in numarray, but is there a good way to do it in Numeric?
In matlab, you could do a(rind, cind)=b; Is there some reshape, put magic I can do to make this efficient in Numeric?
Thanks, John Hunter
