说明：  本人的数值分析课程设计 ，比较完整！Gauss顺序消去法与Gauss列主元消去法是计算机上常用来求解线性方程组的一种直接的方法。就是在不考虑舍入误差的情况下，经过有限步的四则运算可以得到线性方程组的准确解的一类方法。
(Numerical analysis of the curriculum design, a relatively complete! Gauss law and order eliminate Gauss out PCA elimination method is commonly used computers to solve linear equations in a direct way. Is not consider rounding error of circumstances, and after limited to the four-step operation can be linear equations the exact solutions of a class method.)
