### Conclusion: Gaussianelimination

For a group of polynomial equations (in the Augmented Matrix, X [I, n + 1] represents the values of formulas, and X [I, j] represents the coefficients of the J items of the I equation, here, the Augmented Matrix may not necessarily be N, but may be less; opt indicates the operation rule ): (X [1, 1] * A [1]) OPT (X [1, 2] * A [2]) opt... opt (X [1, N] * A [n]) = x [1, n + 1] (X [2, 1] * A [1]) OPT (X [2, 2] * A [2]) opt... opt (X [2, N] * A [n]) = x [2, n + 1] ...

### Poj1830-Use of Gaussianelimination method (good)

First, let's talk about Gaussian elimination: it refers to the process of converting the Augmented Matrix into an upper triangle matrix and then determining the solution. Assume that a * x = B. A is a matrix of N * m, X is the solution matrix of M * 1, and B is the coefficient matrix of N * 1. Then, the Augmented Matrix is a matrix of N * (m + 1. There are three situations after

### Detailed explanation of the use of Gaussianelimination method in C Language

People who have studied mathematics know that Gaussian elimination method is used to solve linear equations. The algorithm is very simple, but the process is very complicated, this is why I cannot find a free and correct Gaussian elimination method on the Internet. So I made up my mind to compile it myself.Gaussian
