If an iden.y matrix is the answer to a problem under matrix multiplication, then each of the two matrices is an inverse matrix of the other. The matrix which when multiplied by the original matrix gives the iden.y matrix as the solution..
In mathematics, an iden.y element or neutral element is a special type of element of a set with respect to a binary operation on that set, which leaves other elements unchanged when combined with them. This concept is used in alge.ic structures such as groups and rings.The term iden.y element is often shortened to iden.y as will be done in .The definition in the previous section generalizes the notion of inverse in group relative to the notion of iden.y. It's also possible, albeit less obvious, to generalize the notion of an inverse by dropping the iden.y element but keepingociativity, i.e., in a semigroup In a semigroup S an element x ised von Neumann regular if there exists some .Inverse of a Matrix Matrix Inverse Multiplicative Inverse of a Matrix For a square matrix A, the inverse is written A1. When A is multiplied by A1 the result is the iden.y matrix I. Nonsquare matrices do not have inverses Note: Not all square matrices .In this section we will give a brief review of matrices and vectors. We will look at arithmetic involving matrices and vectors, finding the inverse of a matrix, computing the determinant of a matrix, linearly dependent/independent vectors and converting systems of equations into matrix form..

Inverse Element Wikipedia
In abstract alge., the idea of an inverse element generalises concepts of a negation sign reversal in relation to addition, and a reciprocal in relation to multiplication.The intuition is of an element that can 'undo' the effect of combination with another given element. While the precise definition of an inverse element varies depending on the .
