• 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.

 `# 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 :

 `# 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.]]
