numpy.polynomial.hermite_e.
hermegrid3d
(x, y, z, c)[源代码]¶ Evaluate a 3D HermiteE series 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:  x, y, z : array_like, compatible objects
The three dimensional series is evaluated at the points in the Cartesian product of x, y, and z. If x,`y`, or z is a list or tuple, it is first converted to an ndarray, otherwise it is left unchanged and, if it isn’t an ndarray, it is treated as a scalar.
 c : array_like
Array of coefficients ordered so that the coefficients for terms of degree i,j are contained in
c[i,j]
. If c has dimension greater than two the remaining indices enumerate multiple sets of coefficients.
Returns:  values : ndarray, compatible object
The values of the two dimensional polynomial at points in the Cartesian product of x and y.
