Python | Numpy np.lagval2d() method

Last Updated : 23 Jan, 2020

With the help of np.lagval2d() method, we can get the 2-D laguerre series at point x by using np.lagval2d() method.

Syntax : np.lagval2d(x, y, c) Return : Return the 2-D laguerre series at point x and y.

Example #1 : In this example we can see that by using np.lagval2d() method, we are able to get the 2-D laguerre series at point x and y by using this method.

Python3 1=1

# import numpy and lagval2d
import numpy as np
from numpy.polynomial.laguerre import lagval2d

x = np.array([[1, 2], [3, 4]])
y = np.array([[5, 10], [15, 20]])
c = np.array([1, 2])

# import np.lagval2d() method
gfg = lagval2d(x, y, c)

print(gfg)

Output :

[[13. 44.] [43. 94.]]

Example #2 :

Python3 1=1

# import numpy and lagval2d
import numpy as np
from numpy.polynomial.laguerre import lagval2d

x = np.array([[1, 2], [3, 4]])
y = np.array([[-1, -2], [-3, -4]])
c = np.array([1, -2])

# import np.lagval2d() method
gfg = lagval2d(x, y, c)

print(gfg)

Output :

[[11. 24.] [21. 38.]]
