MC13D: a Fortran subroutine for finding symmetric permutations to block triangular form. That is, given the column numbers of the nonzeros in each row of a sparse matrix, this subroutine finds a symmetric permutation that makes the matrix block lower triangular. (See I.S. Duff and J.K. Reid, ACM TOMS 4 (1978) pp. 189-192.). Classes : D2e . Operations associated with the solution of systems of linear equations, including matrix inverses, and LU and related factorizations (e.g., matrix reorderings) Type : Fortran software in TOMS collection. Access : Some uses prohibited. Portable. Precision: Single. Usage : CALL MC13D(N, ICN, LICN, IP, LENR, IOR, IB, NUM, IW) Details : Fullsource Sites : (1) NETLIB
