np.lagub()
方法用於將一個Laguerre級數減去另一個Laguerre級數,它返回兩個Laguerre級數的差c1 - c2.
用法:np.lagub(c1, c2)
參數:
c1, c2 :[ array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high.
返回:[ndarray]代表它們差異的Laguerre級數係數。
代碼1:
# Python program explaining
# numpy.lagsub() 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.lagsub() method
res = geek.lagsub(s1, s2)
# Resulting laguerre series
print (res)
輸出:
[ 1. 1. 3.]
代碼2:
# Python program explaining
# numpy.lagub() 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.lagsub() method
res = geek.lagsub(s1, s2)
# Resulting laguerre series
print (res)
輸出:
[ 8. 16. 24. 32. 40.]
