Python | Numpy np.chebmul() method

Last Updated : 03 Nov, 2019

With the help of np.chebmul() method, we can get the multiplication of two Chebyshev series by using np.chebmul() method.

Syntax : np.chebmul(s1, s2) Return : Return an array after multiplication.

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

Python3 1=1

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

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

print(gfg)

Output :

[55. 79. 67. 41. 28.]

Example #2 :

Python3 1=1

# 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.chebmul() method
gfg = C.chebmul(s1, s2)

print(gfg)

Output :

[ 77. 114.5 110. 113. 92. 70. 58. 46.5 14. 19. 15. ]
