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.]] Comment More infoAdvertise with us Next Article Python | Numpy np.lagint() method J Jitender_1998 Follow Improve Article Tags : Technical Scripter Python Python numpy-polynomials Practice Tags : python Similar Reads Python | Numpy np.lagfit() method With the help of np.lagfit() method, we can get the least squares fit of laguerre series of a given data by using np.lagfit() method.
