【问题描述】已知线性方程组AX=B,求解该方程组。参考算法:
消去法:将列向量B加到矩阵A的最后一列,构成增广矩阵AB。对AB进行下列三种初等变换,使原矩阵A的部分的主对角线上的元素均为1,其余元素均为0,则原列向量B的部分即为X的值:
1. 将矩阵的一行乘以一个不为0的数
2. 将矩阵的一行加上另一行的倍数
3. 交换矩阵中两行的位置

用高斯列主元消元法解下列线性方程组
高斯消元求解一些系数矩阵中含有极小数的情况下,会产生巨大的舍入误差,导致算法失效。一个简单而有效的改进方法是每次在进行将当前列中元素的消成0的运算时,选择当前列j对应的行(j to n)中绝对值较大的一个数作为主元行,这样,误差就会减小很多,PCA with out Gaussian elimination method solution of the following system of linear equations to solve a numbe

在求解线性方程组(System of Linear Equations)的算法中,有两类最基本的算法,一类是直接法,即以消去为基础的解法。如果不考虑误差的影响,从理论上讲,它可以在固定步数内求得方程组的准确解。另一类是迭代解法,它是一个逐步求得近似解的过程,-we can use several different methods to obtain a solution. If a unique solution is known to exist, and the coefficient m
