numpy.polynomial.hermite_e.
hermegrid2d
(x, y, c)[source]¶ Evaluate a 2D HermiteE series on the Cartesian product of x and y.
This function returns the values:
where the points (a, b) consist of all pairs formed by taking a from x and b from y. The resulting points form a grid with x in the first dimension and y in the second.
The parameters x and y are converted to arrays only if they are tuples or a lists, otherwise they are treated as a scalars. In either case, either x and y or their elements must support multiplication and addition both with themselves and with the elements of c.
If c has fewer than two dimensions, ones are implicitly appended to its shape to make it 2D. The shape of the result will be c.shape[2:] + x.shape.
Parameters:  x, y : array_like, compatible objects
The two dimensional series is evaluated at the points in the Cartesian product of x and y. If x or y 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.
