通过矩阵秩方法工具给出了使用初等变换计算矩阵群逆的方法,从理论上统一了奇异矩阵群逆和可逆矩阵逆的计算方法,并给出算例.
Method of elementary transformation to compute Group inverse is given by applying the tool of matrix rank method,which integrates the computaion of the group inverse of singular matrix and the inverse of nonsingular matrix theoretically.An example is also present to illustrate this method.
