Module SPARSE in SPARSE Module SPARSE in SPARSESolves large sparse systems of real or complex linear equations. Can also solve transposed systems, find determinants, and estimate errors. Originally written for use in circuit simulators and is particularly apt at handling node- and modified-node admittance matrices.
