Abstract

A simple method for computing the inverse of Vandermonde matrices is presented. The inverse is obtained by finding the cofactor matrix of Vandermonde matrices. Based on this, it is directly possible to evaluate the determinant and inverse for more general Vandermonde matrices.

Keywords: Vandermonde matrix; inverse of a matrix; determinant of a matrix.
