inverse这里指的是求这个3阶方阵的逆阵。具体方法就是初等变化，如果你会的话，方法如下：假设这个方阵是A，3阶的单位方阵为E，那么 A|E-->E|B。这里的B就是所求的逆阵。做法就是利用行初等变化把A变成E，同时用相同的行初等变化就把E变成了B。在理论上很好解释。这一系列的行变化就相当于B*...

matrix polynomial inversion/ B0210 Algebra C1110 AlgebraAn explicit representation is obtained for P( z) 1 when P( z) is a complex n× n matrix polynomial in z whose coefficient of the highest power of z is the identity matrix. The representation is a sum of terms involving negative ...
Matrix Inverse Multiplicative Inverse of a Matrix For a square matrix A, the inverse is written A-1. When A is multiplied by A-1 the result is the identity matrix I. Non-square matrices do not have inverses.Note: Not all square matrices have inverses. A square matrix which has an ...
