| Abstract: | By using the Moore-Penrose inverse of matrix, this paper gives two expressions forthe inverse matrix of nonsigular partitioned matrix( ), where there are no restrictionsfor A, B, C, D. As the application of the results, this paper gives the expressions ofC, D in the inverse M~(-1) = C + iD of complex matrix M = A + iB. |
