solves sparse linear systems in exact arithmetic
Suitesparse is a collection of libraries for computations involving sparse matrices.
SPEX Left LU is a software package designed to exactly solve unsymmetric sparse linear systems, Ax = b, where A, b and x contain rational numbers. This package performs a left-looking, roundoff-error-free (REF) LU factorization PAQ = LDU, where L and U are integer, D is diagonal, and P and Q are row and column permutations, respectively. Note that the matrix D is never explicitly computed nor needed; thus this package uses only the matrices L and U.
This package relies on GNU GMP and MPRF for exact arithmetic computations.
