Python | Numpy np.legadd() method

np.legadd() method is used to add one Legendre series to another.It returns the sum of two Legendre series c1 + c2.

Syntax : np.legadd(c1, c2)
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Legendre series coefficients ordered from low to high.

Return : [ndarray] Array representing the Legendre series of their sum.

Code #1 :

# Python program explaining
# numpy.legadd() 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 = (1, 3, 5)
s2 = (2, 4, 6)

# using np.legadd() method
res = geek.legadd(s1, s2)

# Resulting legendre series
print (res)

Output:

[  3.   7.  11.]

Code #2 :

# Python program explaining
# numpy.legadd() 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.legadd() method
res = geek.legadd(s1, s2)

# Resulting legendre series
print (res)

Output:

[ 12.  24.  36.  48.  60.]
