Introduce This lecture looks at matrix multiplication from five different points of view. We then learn how to find the inverse of a matrix using elimination, and why the Gauss-Jordan method works. Summary 矩阵的乘法的几种方法(列方法,行方法,列乘行) 矩阵的分块乘法 矩阵的逆以及如何求逆矩阵 C...
However, to find the inverse of the matrix, the matrix must be a square matrix with the same number of rows and columns. There are two main methods to find the inverse of the matrix: Method 1: Using elementary row operations Recalled the 3 types of rows operation used to solve linear ...

The key point of inverse of a product AB is the reverse order. We can calculate A-1 by Gauss-Jordan elimination. The Gauss-Jordan method: 1) construct the augmented matrix [A I]; 2) change to upper triangular by elimination; 3) divide each row by its pivot. The first half of the ...

序言节选: Even a supercomputer doesn't want the inverse matrix: too slow. Inverses gives the simpliest formula x=A^(-1)b but not the top speed. And everyone must know that determinants are even slower-there is no way a linear algebra course should begin wi... (展开) 13 3回应 Wei...
