OOF2: The Manual
Direct (BasicDirect) — Solve matrix equations with a direct method. Not recommended for large problems.
BasicDirect is a matrix equation
solver used in BasicSolverMode. It uses the LAPACK
function to solve equations via LU decomposition. This requires the
matrix to to converted from the sparse format used in OOF2 to a
full represention, which uses a lot of memory. It may be faster and
more accurate for small matrices, however.
