Web9 de dez. de 2013 · In Section 4, we use our result to find the Drazin inverse of block matrix and also to find the expression for when the generalized Schur complement is nonsingular, which can be regarded as the generalizations of some results given in [ 5, 20 ]. Finally, in Section 5, we give two numerical examples to illustrate our results of block … Web1 de jan. de 2024 · Download Citation On Jan 1, 2024, Yingying Qin and others published On the Drazin inverse and M-P inverse for sum of matrices Find, read and cite all the … Web17 de set. de 2024 · The part before “is” states that we take the transpose of a matrix, then find the inverse. The part after “is” states that we find the inverse of the matrix, then take the transpose. Since these two statements are linked by an “is,” they are equal.
