Check if matrix is orthonormal
Did you know?
WebWe know that the matrix C that transforms from an orthonormal non standard basis B to standard coordinates is orthonormal, because its column vectors are the vectors of B. But since C^-1 = C^t, we don't yet know if C^-1 is orthonormal. All we know is that its r o w vectors are an orthonormal set. WebMay 7, 2014 · if you want to check that matrix is approximately orthonormal (by this I mean that the matrix that we get after 'U.T @ U' is nearly equal to an identity matrix), …
WebApr 5, 2024 · The orthonormal discrete Legendre polynomials are introduced as suitable family of basis functions to find the solution of these equations.
