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 $A={\left\{a_{ij}\right\}}_{n\times n}$ and an $n$-vector $B$ (or an $n\times s$ 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
