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 :

import numpy as np

import numpy.polynomial.legendre as geek

s1 = ( 2 , 4 , 8 )

s2 = ( 1 , 3 , 5 )

res = geek.legsub(s1, s2)

print (res)

Code #2 :

import numpy as np

import numpy.polynomial.legendre as geek

s1 = ( 10 , 20 , 30 , 40 , 50 )

s2 = ( 2 , 4 , 6 , 8 , 10 )

res = geek.legsub(s1, s2)

print (res)

Output:

[ 8. 16. 24. 32. 40.]
