Python | Numpy np.polygrid2d() method Last Updated : 29 Dec, 2019 Comments Improve Suggest changes Like Article Like Report np.polygrid2d() method is used to evaluate a 2-D polynomial series on the Cartesian product of x and y. Syntax : np.polygrid2d(x, y, c) Parameters: x, y :[array_like]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]arrays of coefficient polynomial series. Return : [ndarray] The values of the two dimensional polynomial series at points in the Cartesian product of x and y.
