Method Detail

cs_symperm

public static Dcs_common.Dcs cs_symperm(Dcs_common.Dcs A,
                                        int[] pinv,
                                        boolean values)

Permutes a symmetric sparse matrix. C = PAP' where A and C are symmetric.

Parameters:

A - column-compressed matrix (only upper triangular part is used)

pinv - size n, inverse permutation

values - allocate pattern only if false, values and pattern otherwise

Returns:

C = PAP', null on error
