When two vectors are said to be orthogonal, it means that they are perpendicular to each other. When these vectors are represented in matrix form, their product gives a square matrix.

WebAn orthogonal matrix is a square matrix A if and only its transpose is as same as its inverse. i.e., A T = A-1, where A T is the transpose of A and A-1 is the inverse of A. From this definition, we can derive another definition of an orthogonal matrix. Let us see how. A T = A-1. Premultiply by A on both sides, AA T = AA-1,. We know that AA-1 = I, where I is …
