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.
