【摘要】 针对传统LSQR反演算法计算时间长、占用内存大的不足,这里提出了一种LSQR的快速算法,通过线性三元组存储稀疏矩阵,实现相应的矩阵运算,使LSQR算法的运算速度及内存占用都有较大地改善。更多还原

【Abstract】 In this paper,we propose a new LSQR calculation method,which uses a triad table to store sparse matrix,and all matrix operation is based on the triad table.Compared with traditional LSQR method,this method is more superior in the respect of both computing time and memory consumption.更多还原
