In Linear Algebra, a Vandermonde matrix, named after Alexandre-Théophile Vandermonde, is a  matrix with the form:

with entries , the jth power of the number , for all indices  and  where  and  start at 0. Most authors define the Vandermonde matrix as the transpose of the above matrix.

 Applications 
Vandermonde matrices are commonly used in introductory Linear Algebra courses to prove least squares solutions.
