对任意线性方程组AX=B，利用矩阵等价变换形成上三角矩阵，在利用高斯消元法中的回代过程简便的求解方程组AX=B的解。本程序是用MATLAB编写的，运行时只要输入矩阵A和B，即可得到方程的解。程序中有详细的注释，很好理解。本程序具有通用性。-For any system of linear equations AX = B, the use of equivalent transformation matrix to form the upper triangular matrix using Gaussian elimination in the back substitution process of solving simple equations AX = B solution. This procedure is used MATLAB, running as long as the input matrix A and B, can be obtained equations. Detailed program notes, well understood. The program is versatile.
