Python | Numpy np.lagint() method (original) (raw)

Last Updated : 12 Dec, 2019

With the help of **np.lagint()** method, we can get the laguerre series in the form of an array by using np.lagint() method.

Syntax : np.lagint(array of coefficient) Return : Return the array of laguerre series.

**Example #1 :**In this example we can see that by using np.lagint() method, we are able to get the laguerre series in the form of an array.

Python3 1=1 `

import numpy

from numpy.polynomial.laguerre import lagint

using np.lagint() method

gfg = lagint([1, 2, 3])

print(gfg)

`

Output :

[ 1. 1. 1. -3.]

Example #2 :

Python3 1=1 `

import numpy

from numpy.polynomial.laguerre import lagint

using np.lagint() method

gfg = lagint([[1, 2, 3], [4, 5, 6]])

print(gfg)

`

Output :

[[ 1. 2. 3.] [ 3. 3. 3.] [-4. -5. -6.]]
