VandermondeMatrix[{x1, x2, ..., xn}] gives an n×n Vandermonde matrix corresponding to the nodes xi.

• VandermondeMatrix[{x1, x2, ..., xn}, k] gives an n×k Vandermonde matrix.
• VandermondeMatrix[vmat] converts a Vandermonde matrix vmat to a structured array.

Examples

VandermondeMatrix[{1, 2, 3}]

VandermondeMatrix[{a, b, c, d}, 3]
