A Fast Converse Algorithm Based on Two Integrals of the Matries

基于两个矩阵方程 ,讨论了矩阵的一种快速求逆算法 .在考虑矩阵的对称性、稀疏性及减缩部分逆阵元素后 ,推导出逆阵块元素B11、B12 和B2 2 的计算公式并给出算法程序实现方案与算例 。

A fast converse algorithm of the matries based on two integrals of the matries is presented. Considering the symmetry of matrix,sparseness and reducing to partial elements of converse matrix, the formula for converse matrices pieces of elements B 11 ?B 12 and B 22 has been developed. The achievable scheme with algorithmic procedures and example of count are given. This is an effective calculable method for better marginal decreasement of memory space of computer.
