Python | Numpy np.chebmulx() method

With the help of np.chebmulx() method, we can get the multiplication of Chebyshev series with independent variable x by using np.chebmulx() method.

Syntax : np.chebmulx(s1)
Return : Return an array after multiplication with x.

Example #1 :
In this example we can see that by using np.chebmulx() method, we are able to get the multiplication of chebyshev series with an independent variable x using this method.

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

s1 = (4, 6, 8)

# using np.chebmulx() method
gfg = C.chebmulx(s1)

print(gfg)

Output :

[3. 8. 3. 4.]

Example #2 :

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

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

# using np.chebmulx() method
gfg = C.chebmulx(s1)

print(gfg)

Output :

[3. 8. 3.5 5.5 3. 1.5 2.5]
