Python | Numpy np.lagval3d() method

Last Updated : 23 Jan, 2020

With the help of np.lagval3d() method, we can get the 3-D laguerre series at point x by using np.lagval3d() method.

Syntax : np.lagval3d(x, y, z, c)
Return : Return the 3-D laguerre series at point x, y and z.

Example #1 :
In this example we can see that by using np.lagval3d() method, we are able to get the 3-D laguerre series at point x, y and z by using this method.

# import numpy and lagval3d 
import numpy as np 
from numpy.polynomial.laguerre import lagval3d 
  
x = np.array([[1, 2], [3, 4]]) 
y = np.array([[-5, -10], [-15, -20]]) 
z = np.array([[1, 2], [3, 4]]) 
c = np.array([1, 2]) 
  
# import np.lagval3d() method 
gfg = lagval3d(x, y, z, c) 
  
print(gfg) 

Output :

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

Example #2 :

# import numpy and lagval3d 
import numpy as np 
from numpy.polynomial.laguerre import lagval3d 
  
x, y, z = 1, 2, 3
c = np.array([1, 2]) 
  
# import np.lagval3d() method 
gfg = lagval3d(x, y, z, c) 
  
print(gfg) 

Output :

1.0
