Python | Numpy np.chebint() method

  • Last Updated : 12 Dec, 2019

With the help of np.chebint() method, we can get the integration value of chebyshev series in the form of an array having value of coordinates using np.chebint() method.

Syntax : np.chebint(series, value)
Return : Return an array having coordinates of series after integration.

Example #1 :
In this example we can see that by using np.chebint() method, we are able to get the integration of chebyshev series and it will return an array having coordinates of it.




# import numpy
import numpy as np
from numpy.polynomial import chebyshev as C
  
x = np.array([1, 2, 3])
# using np.chebint() method
gfg = C.chebint(x, 2)
  
print(gfg)

Output :

[-0.3125      0.25       -0.25        0.08333333  0.0625    ]

Example #2 :




# import numpy
import numpy as np
from numpy.polynomial import chebyshev as C
  
x = np.array([2, 5, 7, 11])
# using np.chebint() method
gfg = C.chebint(x, 2)
  
print(gfg)

Output :

[-0.8125     -2.125      -0.66666667 -0.47916667  0.14583333  0.1375    ]
