A New Implementation of Sparse Gaussian Elimination
Robert Schreiber · ACM Transactions on Mathematical Software · 1982
An lmplementat]on of sparse LDL T and LU factorlzatlon and back substitution, based on a new scheme for storing sparse matrmes, is presented.The new method appears to be as efficmnt m terms of work and storage as existing schemes It is more amenable to efficmnt implementation on fast plpehned scmntlfic computers Categories and Subject Descriptors: G.
