A Matrix Library

Overview

This library defines an interface for matrices and includes a dense and sparse matrix implementation of the interface.

Relevant Files

TABLE.sml: Defines the interace.

Dense Matrices: Dense implementation of matrices of real numbers based on the Array2 structure from the basis library.

Sparse Matrices: Represents sparse matrices as a table of tables of reals. The toplevel table has an entry for each non-empty row, and each second-level table has an entry for each non-zero within the row. Currently the solve function only works on symmetric matrices.
