[Pysparse-developers] Addition to pysparse

[Roman G. <rom...@gm...>]

Hi all

I just received word from Ed Schofield, that he commited some nice
additions to CVS:

----------------------------
I've just committed some changes to ll_mat.c to support operations
iterating over non-zeros elements.  Here's the changelog:

revision 1.3
date: 2005/04/28 11:50:31;  author: edschofield;  state: Exp;  lines:
+202 -0
Added routines for ll_mat objects:
    (1) scaling by a constant ("scale")
    (2) getting the indices of all non-zero elements ("keys")
    (3) getting all non-zero elements ("values")
    (4) getting a list of (index, value) pairs of non-zero elements
("items")

These routines currently only support non-symmetric matrices.
