Python Numpy np.lagmul()用法及代码示例

np.lagmul()方法用于将一个Laguerre级数与另一个Laguerre级数相乘，返回两个Laguerre级数的乘积c1 * c2.

用法： np.lagmul(c1, c2)

参数：

c1, c2  :[  array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high.

返回：[ndarray]代表其乘积的Laguerre级数系数。

代码1：

# Python program explaining 
# numpy.lagmul() method  
    
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
    
# Laguerre series coefficients 
  
s1 = (2, 4, 8)  
s2 = (1, 3, 5)    
    
# using np.lagmul() method  
res = geek.lagmul(s1, s2)  
  
# Resulting laguerre series 
print (res)

输出：

[  54.  -86.  266. -348.  240.]

# Python program explaining 
# numpy.lagmul() method  
    
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
    
# Laguerre series coefficients 
s1 = (10, 20, 30, 40, 50)  
s2 = (2, 4, 6, 8, 10)     
    
# using np.lagmul() method  
res = geek.lagmul(s1, s2)  
  
# Resulting laguerre series 
print (res)

输出：

[   1100.   -1600.   10400.  -36000.   90600. -152400.  169400. -112000.
   35000.]
