Sparse1.3 is a flexible package of subroutines written in C used to quickly and accurately solve large sparse systems of linear equations. The package is able to handle arbitrary real and complex square matrix equa- tions. Besides being able to solve linear systems, it is also able to quickly solve transposed systems, find determinants, and estimate errors due to ill-conditioning in the system of equations and instability in the computations.
Sparse also provides a test program that is able read matrix equations from a file, solve them, and print useful information about the equation and its solution. Sparse1.3 is generally as fast or faster than other popular sparse matrix packages when solving many matrices of similar structure. Sparse does not require or assume symmetry and is able to perform numerical pivot- ing to avoid unnecessary error in the solution. It handles its own memory allocation, which allows the user to forgo the hassle of providing adequate memory.
