numpy.polynomial.chebyshev.chebvander3d(x, y, z, deg)[source] -
Pseudo-Vandermonde matrix of given degrees.
Returns the pseudo-Vandermonde matrix of degrees
degand sample points(x, y, z). Ifl, m, nare the given degrees inx, y, z, then The pseudo-Vandermonde matrix is defined by![V[..., (m+1)(n+1)i + (n+1)j + k] = T_i(x)*T_j(y)*T_k(z),](https://docs.scipy.org/doc/numpy-1.13.0/_images/math/7ba6300a34091029c0e6e1d5d240cc0096485df7.png)
