numpy.polynomial.legendre.legvander2d(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

$V[..., deg[1]*i + j] = L_i(x) * L_j(y),$

where 0 <= i <= deg[0] and 0 <= j <= deg[1]. The leading indices of V index the po
