= 3+ 6 − 5 = 4 Orthogonal Matrices: Only square matrices may be orthogonal matrices, although not all square matrices are orthogonal matrices. An orthogonal matrix satisfied the equation AAt = I Thus, the inverse of an orthogonal matrix is simply the transpose of that matrix. Orthogonal matrices are very important in factor analysis.
