高斯列主元消去法，用c#编写的高斯消去法。-Gaussian elimination pivot column, using c# written in Gaussian elimination.

列主元高斯消去法对于某电路的分析，归结为求解线性方程组RI=V。其中 （1）编制解n阶线性方程组 列主元高斯消去法的通用程序； （2）用所编制程序解线性方程组 ，并打印出解向量，保留5位有效数； -Out the main element Gaussian elimination of a certain circuit analysis, reduced to solving linear equations RI = V. Where (a) the prepar

列主元法的基本思想是依次对k=1,2,……,n通过有选择地互换方程组中两个方程的位置，把akk,a(k+1)k,……,ank中绝对值最大的元素移到主对角线来，从而改造了高斯消去法的性能。-Out the main element of the basic idea is to turn on the k = 1,2, ... ..., n by selective exchange of equations two equations position to akk, a (k+1) k, ..
