求解大型对称或非对称方程组，采用稀疏矩阵存储及求解算法，在电力系统仿真分析软件中得到应用-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 hass
