btf-1.1.0-1mdv2010.0.src.rpm

Description:

BTF is a software package for permuting a matrix into block upper
triangular form. It includes a maximum transversal algorithm, which
finds a permutation of a square or rectangular matrix so that it has a
zero-free diagonal (if one exists); otherwise, it finds a maximal
matching which maximizes the number of nonzeros on the diagonal. The
package also includes a method for finding the strongly connected
components of a graph. These two methods together give the
permutation to block upper triangular form.
