چکیده
|
A matrix has an ordinary inverse only if it is square, and even then only if it is nonsingular or, in other words, if its columns (or rows) are linearly independent. in recent years needs have been felt in numerous areas of applied mathematics for some kind of partial inverse of a matrix that is singular or even rectangular. in this paper, some results on the quasi-commuting inverses, are given and the effiect of them in solving the case of linear system of equations where the coefficient matrix is a singular matrix, is illustrated.
