Witryna27 mar 2024 · The third special type of matrix we will consider in this section is the triangular matrix. Recall Definition 3.1.6 which states that an upper (lower) triangular matrix contains all zeros below (above) the main diagonal. Remember that finding the determinant of a triangular matrix is a simple procedure of taking the product of the … WitrynaIn other words, when the product of the real square matrix and its transpose is equal to an identity matrix, the real square matrix is said to be an orthogonal matrix. Let A be the square matrix, AT is the transpose of A and A-1 is the inverse of A. If A T = A-1. then AA T = A T A = I. Here, I is the identity matrix. Also Read:
