## What is Orthogonal Matrix? Determinant & Examples

Orthogonal matrix is a square matrix R=[xij] such that RT = R-1. In other words, a square matrix (R) whose transpose is equal to its inverse is known as orthogonal matrix i.e. RT = R-1. Orthogonal matrix examples The best example of an orthogonal matrix is an identity matrix or unit matrix as shown below. The … Read more
