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 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 ])
gfg = lagval2d(x, y, c)
print (gfg)
|
Output :
[[13. 44.]
[43. 94.]]
Example #2 :
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 ])
gfg = lagval2d(x, y, c)
print (gfg)
|
Output :
[[11. 24.]
[21. 38.]]
