np.leggrid2d() method is used to evaluate a 2-D legendre series on the Cartesian product of x and y.
Syntax :
np.leggrid2d(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] 1-D arrays of legendre series coefficients ordered from low to high.Return : [ndarray] The values of the two dimensional legendre series at points in the Cartesian product of x and y.
Code #1 :
# Python program explaining # numpy.leggrid2d() method   # importing numpy as np   import numpy as np from numpy.polynomial.legendre import leggrid2d   # Input legendre series coefficients c = np.array([[1, 3, 5], [2, 4, 6]])   # using np.leggrid2d() method ans = leggrid2d([7, 9], [8, 10], c) print(ans) |
Output:
[[ 4751.5 7351.5] [ 5965.5 9229.5]]
