大型稀疏线形方程组的快速求解，直接分解求解-large sparse linear equations for the rapid, direct decomposition solution

对于阶数不高的方程组，直接法非常有效，对于阶数高，而系数矩阵稀疏的线性方程组却存在着困难，在这类矩阵中，非零元素较少，若用直接法求解，就要存贮大量零元素。为减少运算量、节约内存，使用迭代法更有利。-The order of the equations is not high, the direct method is very effective for high order, and the sparse coefficient matrix of linear equations, ther
