Variations on the Theme of Gaussian Elimination
借助因子空间或商空间的概念，揭示了高斯消元法的几何解释，并据此提出了两种新的求解线性代数方程的方法。
The standard method of Gaussian elimination for the solution of linear algebraic equations is shown, with the aid of the concept of the factor or quotient space, to have a geometrical interpretation. This suggests alternative methods for the solution of equations of this type, and two new methods are described.
