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.]
