BASICLU implements a sparse LU factorization and an update method that maintains the factorization after column changes to the matrix. It is intended for use in simplex-type algorithms and has been tailored to hypersparse linear programming problems. The algorithm is described in is tailored to linear programming basis matrices, which often are very sparse. It provides routines for solving linear systems with a dense or sparse right-hand side.
