np.leggrid3d() method is used to evaluate a 3-D legendre series on the Cartesian product of x, y and z.
np.leggrid3d(x, y, z, c)
x, y, z :[array_like]The three dimensional series is evaluated at the points in the Cartesian product of x, y and z. If x or 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] legendre series coefficients.
Return : [ndarray] The values of the two dimensional legendre series at points in the Cartesian product of x and y.
