Description
- This function gives the matrix with the property of vandermonde.
- A Vandermonde matrix is a matrix presents a geometric progression in every row or in every column with the first element being 1.
- A Vandermonde matrix of order n is of the form:

- A Vandermonde matrix is sometimes also called an alternant matrix.
- Users can assign the numbers for vandermonde matrix. For e.g.,MATRIX("vandermonde",10,1..10)
