Python| Numpy 多项式 legline() 方法

np.legline()方法用于查找其图形为直线的勒让德级数。

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.

代码#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)  

输出：

[2 3]

代码#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)

输出：

[1 4]
