Hi,
I would like to update inplace a CSC sparse Matrix A
which has several bands like
A = spdiagm( 0 => ones(10), 1=> ones(10-1))
What I would like to do is to change the values of the band 1
(for example) by modifying A.nzval
. The only solution I can see for this is using a composite type to save the indices of the bands which correspond to the encoding used for A.nzval
.
Before I embark into coding this, I was wondering if anybody has done ever done, or has a better solution.
Thank you for your help,
