Python | Numpy polynomial lagline() method

np.lagline() method is used to find a Laguerre series whose graph is a straight line.

Syntax : np.lagline(off, scl)
Parameters:
off, scl :[scalar] The specified line is given by off + scl*x.

Return : [ndarray] Laguerre series coefficient array for the resulting line.

Code #1 :

# Python program explaining
# numpy.lagline() method

# importing numpy as np
# and numpy.polynomial.laguerre module as geek
import numpy as np
import numpy.polynomial.laguerre as geek

# using np.lagline() method
res = geek.lagline(2, 3)

# Resulting Laguerre series
print (res)

Output:

[ 5 -3]

Code #2 :

# Python program explaining
# numpy.lagline() method

# importing numpy as np
# and numpy.polynomial.laguerre module as geek
import numpy as np
import numpy.polynomial.laguerre as geek


# using np.lagline() method
res = geek.lagline(1, 4)

# Resulting laguerre series
print (res)

Output:

[ 5 -4]
