Python | Numpy np.chebsub() method

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
import numpy as np
from numpy.polynomial import chebyshev as C

s1 = (4, 6, 8)
s2 = (3, 5, 7)
# using np.chebsub() method
gfg = C.chebsub(s1, s2)

print(gfg)

Output :

[1., 1., 1.]

Example #2 :

# import numpy
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)
# using np.chebsub() method
gfg = C.chebsub(s1, s2)

print(gfg)

Output :

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