对于阶矩阵,如果存在阶矩阵,使得.则称为可逆矩阵.称为的逆矩阵. 由定义可得,与一定是同阶的,而且如果可逆,则的逆矩阵是唯一的. 这是因为,如果,都是的逆矩阵,则有 , 那么 所以逆矩阵是唯一的.我们把矩阵的逆矩阵记作. 逆矩阵有... (The band matrix, band matrix if it exists, making. Is called invertible matrix. Known as the inverse matrix. By definition available, and must be the same bands, and if reversible, then the inverse matrix is unique. This is because if is the inverse matrix, it has, then the inverse matrix is so unique. we Matrix recorded as the inverse matrix. inverse matrix has ...)
