numpy.polynomial.legendre.legval3d(x, y, z, c)
Evaluate a 3-D Legendre series at points (x, y, z).
This function returns the values:
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 either case, either
z or their elements must support multiplication and addition both with themselves and with the elements of
c has fewer than 3 dimensions, ones are implicitly appended to its shape to make it 3-D. The shape of the result will be c.shape[3:] + x.shape.
x, y, z : array_like, compatible object
The three dimensional series is evaluated at the points
c : array_like
Array of coefficients ordered so that the coefficient of the term of multi-degree i,j,k is contained in
values : ndarray, compatible object
The values of the multidimensional polynomial on points formed with triples of corresponding values from
