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. Python3 1=1
# 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 : Python3 1=1
# 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
