Author: Pier-André Bouchard St-Amant
Package: Matrix new
A summary of the changes made since 11/Nov/2009
Changes :
- Internal convention : zeros are no longer stored in memory. All functions were changed to reflect this. This is transparent to users.
- Performance improvements for large sparse matrices (based on above), mostly for multiplication and inversion.
- Four new functions : utrig, ltrig, diag and smooth : upper triangular matrix, lower triangular matrix, diagonal matrix and smooth small number to zero (see documentation).
- Correction of numerous bugs.
