numpy.polynomial.hermite.hermvander2d(x, y, deg) [source]
Pseudo-Vandermonde matrix of given degrees. Returns the pseudo-Vandermonde matrix of degrees deg and sample points (x, y). The pseudo-Vandermonde matrix is defined by
where 0 <= i <= deg[0] and 0 <= j <= deg[1]. The leading indices of V index the points (x, y) and the last index encodes the degrees of the Hermite polynomials. If V = hermvander2d(x, y, [xdeg, ydeg]), then the columns of V correspond to the elements of a
