np.lagmul()
method is used to multiply one Laguerre series to another.It returns the product of two Laguerre series c1 * c2.
Syntax : np.lagmul(c1, c2)
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high.
Return : [ndarray] Laguerre series coefficients representing their product.
Code #1 :
import numpy as np
import numpy.polynomial.laguerre as geek
s1 = ( 2 , 4 , 8 )
s2 = ( 1 , 3 , 5 )
res = geek.lagmul(s1, s2)
print (res)
|
Output:
[ 54. -86. 266. -348. 240.]
Code #2 :
import numpy as np
import numpy.polynomial.laguerre as geek
s1 = ( 10 , 20 , 30 , 40 , 50 )
s2 = ( 2 , 4 , 6 , 8 , 10 )
res = geek.lagmul(s1, s2)
print (res)
|
Output:
[ 1100. -1600. 10400. -36000. 90600. -152400. 169400. -112000.
35000.]
