Python | Numpy polynomial legline() method

np.legline() method is used to find a Legendre series whose graph is a straight line.

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

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

Code #1 :

# Python program explaining
# numpy.legline() method

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

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

# Resulting legendre series
print (res)

Output:

[2 3]

Code #2 :

# Python program explaining
# numpy.legline() method

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


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

# Resulting legendre series
print (res)

Output:

[1 4]
