摘要
将给出初等ｒ分块循环矩阵可逆的充要条件及逆矩阵的表达式；对奇异的初等ｒ分块循环矩阵给出 Ａ 的一个反射ｇ逆表达式，特别当｜ｒ｜ ＝ １ ，给出 Ａ的 Ｍｏｏｒｅｐｅｎｒｏｓｅ
Gives the necessary and sufficient condition of elementary partition circulant matrices invertibility. And g inverse and Moore penrose generalized inverse of signular elementary r partition circulant matrices are also presented.
