Python | Numpy np.legsub() method
np.legub() method is used to subtract one Legendre series to another.It returns the difference of two Legendre series c1 - c2.
Syntax :
np.legub(c1, c2)
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Legendre series coefficients ordered from low to high.Return : [ndarray] Legendre series coefficients representing their difference.
Code #1 :
# Python program explaining # numpy.legsub() method # importing numpy as np # and numpy.polynomial.legendre module as geek import numpy as np import numpy.polynomial.legendre as geek # Legendre series coefficients s1 = (2, 4, 8) s2 = (1, 3, 5) # using np.legsub() method res = geek.legsub(s1, s2) # Resulting Legendre series print (res) |
Output:
[ 1. 1. 3.]
Code #2 :
# Python program explaining # numpy.legub() method # importing numpy as np # and numpy.polynomial.legendre module as geek import numpy as np import numpy.polynomial.legendre as geek # Legendre series coefficients s1 = (10, 20, 30, 40, 50) s2 = (2, 4, 6, 8, 10) # using np.legsub() method res = geek.legsub(s1, s2) # Resulting Legendre series print (res) |
Output:
[ 8. 16. 24. 32. 40.]
