numpy.polynomial.polynomial.polygrid3d(x, y, z, c)
[source]
Evaluate a 3D polynomial on the Cartesian product of x, y and z.
This function returns the values:
where the points (a, b, c)
consist of all triples formed by taking a
from x
, b
from y
, and c
from z
. The resulting points form a grid with x
in the first dimension, y
in the second, and z
in the third.
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. 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 three dimensions, ones are implicitly appended to its shape to make it 3D. The shape of the result will be c.shape[3:] + x.shape + y.shape + z.shape.
Parameters: 


Returns:
