Direct methods

Abstract
We review current methods for the direct solution of sparse linear equations. We discuss basic concepts such as fill-in, sparsity orderings, indirect addressing and compare general sparse codes for dense systems. We examine methods for greatly increasing the efficiency when the matrix is symmetric positive definite. We consider frontal and multifrontal methods emphasizing how they can take advantage of vectorization, RISC architectures, and parallelism. Some comparisons are made with other techniques and the availability of software for the direct solution of sparse equations is discussed.
