A new row ordering strategy for frontal solver (English)
0 references
The problem of reordering the rows of a general unsymmetric matrix \(A\) for use with a frontal solver is studied. A variant of Sloan's profile reduction algorithm and spectral method are applied to a row graph of an unsymmetric matrix \(A\) to reorder the rows. The author illustrates the effectiveness of her algorithms on several numerical experiments based on industrial and engineering applications.
