摘要
解决了幂等和幂零阵的伴随阵的反问题,把Sherman-Morrison公式[1]推广到求伴随阵的情形,并给出了一类伴随还原阵的简单求法.
The inverse problems for the adjoint matrices of an idempotent and a nilpotent matrices are solved; the formula of Sherman-Morrison is extended to find its adjoint matrix; a short-cut method for finding a kind of adjoint pull back matrix is given.
