To find A^(-1) and to show that AA^(-1)=I.Consider the provided matrix:A=(bmatrix) 4&7 -1&-2(bmatrix) To find A^(-1) use Gauss-Jordan elimination. This is explained below:Consider the provided matrix:A=(bmatrix) 4&7 -1&-2(bmatrix) [(array)(rr|rr)4 & 7 & 1&...
If AA is an n×nn×n matrix and BB is an n×nn×n matrix such that AB=BA=InAB=BA=In, then B=A−1B=A−1, the multiplicative inverse of a matrix AA.Example: Showing That the Identity Matrix Acts as a 1 Given matrix A, show that AI=IA=AAI=IA=A. A=[34−25]A=[34...
答案 elementary matrix也可以是列变换啊上面的方法不适合计算机自动计算,一般都用数值方法计算逆矩阵. 相关推荐 1 关于逆矩阵的问题 请问find the inverse of a matrix using row operation 和 find the inverse of a matrix using elementary matrix 运算有区别么?用row operation也需要用到elementary matrix不是么?
