ladel_col_counts.h File Reference

Detailed Description

Computes the col counts needed for the symbolic factorization (after etree and postorder).

Author

Ben Hermans

The routine in this file computes the column counts of the factor assuming the etree and postordering have been performed prior to this. An alternative (with worse asymptotic complexity) that computes the etree and column counts in one go, is ladel_etree_and_col_counts in ladel_etree.c.
