numpy.polynomial.legendre.legval3d(x, y, z, c)
[source]
Evaluate a 3-D Legendre series at points (x, y, z).
This function returns the values:
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 either case, either x
, y
, and z
or their elements must support multiplication and addition both with themselves and with the elements of c
.
If 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.
Parameters: |
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 |
---|---|
Returns: |
values : ndarray, compatible object The values of the multidimensional polynomial on points formed with triples of corresponding values from |
