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

Last Updated : 03 Nov, 2019

With the help of **np.chebsub()** method, we can get the subtraction of two Chebyshev series by using np.chebsub() method.

Syntax : np.chebsub(s1, s2)
Return : Return an array after subtraction.

Example #1 :
In this example we can see that by using np.chebsub() method, we are able to get the subtraction of two chebyshev series using this method.

import numpy as np

from numpy.polynomial import chebyshev as C

s1 = ( 4 , 6 , 8 )

s2 = ( 3 , 5 , 7 )

gfg = C.chebsub(s1, s2)

print (gfg)

Output :

[1., 1., 1.]

Example #2 :

import numpy as np

from numpy.polynomial import chebyshev as C

s1 = ( 4 , 6 , 8 , 1 , 3 , 5 )

s2 = ( 3 , 5 , 7 , 2 , 4 , 6 )

gfg = C.chebsub(s1, s2)

print (gfg)

Output :

[ 1. 1. 1. -1. -1. -1.]
