matlab 数值分析 列主元消去法 线性方程

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

常用算法C语言编写，包括kalman、线性方程求解等很多很好的算法。-Common algorithms written in C, including the kalman, linear equations, and many good algorithms.
