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 \(\mathbf{A} = {\{a _{ij}\}} _{n \times n}\) and an \(n\)vector \(\mathbf{B}\) (or an \(n \times s\) matrix \(\mathbf{B}\)), this subroutine solves the system \(\mathbf{Ax}=\mathbf{b}\) (\(\mathbf{AX}=\mathbf{B}\)).
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 (RALTR2002024). This can be obtained from the web site
