高斯消去法是求解线性方程组的基础的重要方法，也是计算机上常用的解低阶稠密矩阵方程组的有效方法。，高斯消去法或称高斯－约当消去法，由高斯和约当得名（很多人将高斯消去作为完整的高斯－约当消去的前半部分），它是线性代数中的一个算法，用于决定线性方程组的解，决定矩阵的秩，以及决定可逆方矩阵的逆。当用于一个矩阵时，高斯消去产生“行消去梯形形式”。-Gaussian elimination is the basis for solving linear equations important way, the solution is low-end computer used dense matrix equations in an effective manner. , Gaussian elimination, or Gauss- Jordan elimination, the Gauss and about when the name (many people will be as complete Gaussian elimination Gauss- Jordan elimination in the first half), which is linear algebra an algorithm used to determine the solution of linear equations to determine the rank of matrix, and to determine the inverse of invertible square matrix. When used with a matrix, Gaussian elimination lead to " eliminate the ladder-line form."
