We write A-1 instead of 1A because we don't divide by a matrix! And there are other similarities:When we multiply a number by its reciprocal we get 1: 8× 18 = 1 When we multiply a matrix by its inverse we get the Identity Matrix (which is like "1" for matrices): A× A-1...

We can calculate theInverse of a Matrixby: Step 1: calculating the Matrix of Minors, Step 2: then turn that into the Matrix of Cofactors, Step 3: then the Adjugate, and Step 4: multiply that by 1/Determinant. But it is best explained by working through an example!
matrix. Its inverse, if it exists, is the matrix that satisfies where is the identity matrix. If exists, then we say that is invertible. When , then and which makes clear that the definition above generalizes the notion of reciprocal of a number. ...
inverse of a matrixA–1, it is necessary and sufficient that the determinant of the given matrixAbe nonzero; that is, the matrixAmust be nonsingular. The elementsbijof the inverse of a matrix are found by the formulabij=Aji/D, whereAjiis the cofactor of the elementaijof matrixAandDis...

A stochastic matrix is a square matrix with nonnegative entries and row sums 1. The simplest example is a permutation matrix, whose rows permute the rows of an identity matrix. A permutation matrix and its inverse are both stochastic. We prove the converse, that is, if a matrix and its ...
