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.

# 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 :

# 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.]]
