数学上，高斯消元法（或译：高斯消去法），是线性代数规划中的一个算法，可用来为线性方程组求解。但其算法十分复杂，不常用于加减消元法，求出矩阵的秩，以及求出可逆方阵的逆矩阵。-In mathematics, the Gauss elimination method (or Gauss elimination method) is an algorithm in linear algebra programming, which can be used to solve linear equations. However, the algorithm is very complex, and it is not common to add and subtract element method, and the rank of matrix is obtained.
