چکیده
|
Nonnegativity of the moore-penrose inverse of a perturbation of the form a-xgyt is considered when a†≥0. using a generalized version of the sherman-morrison-woodbury formula,conditions for (a-xgyt) † to be nonnegative are derived. applications of the results are presented briefly. iterative versions of the results are also studied. © 2013 shani jose and k. c. sivakumar.
