where matrix is a square nonsingular matrix. The INV function produces a matrix that is the inverse of matrix, which must be square and nonsingular. However, the SOLVE function is more accurate and ...

Abstract. In this paper, we present the explicit expression for the group inverse of the sum of two matrices. As an application, the explicit expression for the group ...

where matrix is a numeric matrix or literal. The GINV function creates the Moore-Penrose generalized inverse of matrix. This inverse, known as the four-condition inverse, has these properties: ...
