Python | Numpy np.lagmulx() method

With the help of np.lagmulx() method, we can get the multiplication of Laguerre series with x by using np.lagmulx() method, where x is an independent variable.

Syntax : np.lagmulx(series)
Return : Return the coefficient of series after multiplication.

Example #1 :
In this example we can see that by using np.lagmulx() method, we are able to get the coefficient of series after multiplication of Laguerre series with independent variable x by using this method.

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

series = np.array([1, 2, 3, 4, 5])

# using np.lagmulx() method
gfg = lagmulx(series)

print(gfg)

Output :

[ -1. -1. -1. -1. 29. -25.]

Example #2 :

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

series = np.array([10, 20, 30])

# using np.lagmulx() method
gfg = lagmulx(series)

print(gfg)

Output :

[ -10. -10. 110. -90.]
