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

Last Updated : 31 Dec, 2019

**np.legub()** method is used to subtract one Legendre series to another.It returns the difference of two Legendre series c1 - c2.

Syntax : np.legub(c1, c2) Parameters: **c1, c2 :**[ array_like ] 1-D arrays of Legendre series coefficients ordered from low to high.Return : [ndarray] Legendre series coefficients representing their difference.

Code #1 :

Python program explaining

numpy.legsub() method

importing numpy as np

and numpy.polynomial.legendre module as geek

import numpy as np import numpy.polynomial.legendre as geek

Legendre series coefficients

s1 = (2, 4, 8) s2 = (1, 3, 5)

using np.legsub() method

res = geek.legsub(s1, s2)

Resulting Legendre series

print (res)
