numpy.polynomial.chebyshev.chebval3d(x, y, z, c) [source]

Evaluate a 3-D Chebyshev series at points (x, y, z).

This function returns the values:

$p(x,y,z) = \sum_{i,j,k} c_{i,j,k} * T_i(x) * T_j(y) * T_k(z)$

The parameters x, y, and z are converted to arrays only if they are tuples or a lists, otherwise they are treated as a scalars and they must have the same shape after conversion. In
