numpy.polynomial.chebyshev.chebgrid2d(x, y, c) [source]
Evaluate a 2-D Chebyshev 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
