sp_util

Purpose

Sparse matrix utilities.

Description

This function should be used as a mex file. The .m file version does not support all functionalities, is significantly slower and requires more memory.

The mex code is not MATLAB clean, in the sense that it often modifies input arguments. You are thus not encouraged to call sp_util yourself.

The following comments are only provided, so that you can understand the purpose of various calls to sp_util.
