| | + | *<math>order</math> is the size of the Vandermonde matrix. |
| | + | |
| | + | ==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: |
| | + | <math> |
| | + | V=\begin{bmatrix} |
| | + | 1 & \alpha_1 & \alpha_1^2 & \dots & \alpha_1^{n-1}\\ |
| | + | 1 & \alpha_2 & \alpha_2^2 & \dots & \alpha_2^{n-1}\\ |
| | + | 1 & \alpha_3 & \alpha_3^2 & \dots & \alpha_3^{n-1}\\ |
| | + | \vdots & \vdots & \vdots & \ddots &\vdots \\ |
| | + | 1 & \alpha_m & \alpha_m^2 & \dots & \alpha_m^{n-1} |
| | + | \end{bmatrix} </math> |
| | + | *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) |
