ME57 Sparse Hermitian or complex symmetric: multifrontal method

To solve a sparse Hermitian or complex symmetric system of linear equations. Given a sparse Hermitian or complex symmetric matrix A = {aij}n×n and an n-vector B (or an n × s matrix B), this subroutine solves the system Ax = b (AX = B).

ME57 is a complex version of the code MA57 that is described in the technical report “MA57 - a new code for the solution of sparse symmetric indefinite systems” by Duff (RAL-TR-2002-024). This can be obtained from the web site
