On the inversion of the vandermonde matrix
Web15 de nov. de 2024 · As far as I understand, X is an (m x n) matrix, so X^T X is (n x n), so the inversion of a square matrix is enough. (Am I right?) I guess the library provides normal matrix manipulations (multiplication and transpose) for non-square matrices. – http://www.vesnik.math.rs/vol/mv19303.pdf

A simple method for computing the inverse of Vandermonde matrix via … WebWe prove that, more generally, any Vandermonde matrix of a large size is badly ill-conditioned unless its knots are more or less equally spaced on or about the circle { x: x = 1 }. The matrices of the DFT are unitary up to scaling and therefore perfectly conditioned. They are defined by a cyclic sequence of knots, equally spaced on that ...
