The returned list contains array(s) of dtype double, complex double, or

    Remove "small" "trailing" coefficients from a polynomial.

"Small" means "small in absolute value" and is controlled by the

    A generalization of the Vandermonde matrix for N dimensions

        x_k &= \texttt{points[k]} \\
