Python | Numpy np.chebmulx () method



Using the method np.chebmulx() we can get the multiplication of Chebyshev`s series by the independent variable x using np.chebmulx () .

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

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

# NumPy import

import numpy as np

from numpy.polynomial import chebyshev as C

  

s1 = ( 4 , 6 , 8 )

 
# using the np.chebmulx () method

gfg = C.chebmulx (s1)

 

print (gfg)

Output:

[3. 8. 3. 4.]

Example # 2:

# NumPy import

import numpy as np

from numpy.polynomial import chebyshev as C

 

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

 
# using the np.chebmulx () method

gfg = C.chebmulx (s1)

 

print (gfg)
