python編程，python計算實例_python計算熵值法計算實例

import csv

csv_file =csv.reader(open('1.csv','r'))

print(csv_file)

for s in csv_file:

python編程、print(s)

import numpy as np

print(csv_file)

np1 = np.loadtxt(open("1.csv","rb"),delimiter=",",skiprows=0)#原始數據

print(np1)

熵值法。a=np.sum(np1)

a=np.sum(np1,0)#列求和矩陣

print(a)

b=np1/a#運算

print(b)

python3。c=b*np.log(b)#運算

print(c)

k=1/np.log(4)#注意，4方案數

print(k)

d=-k*np.sum(c,0)#運算

java和python、print(d)

e=1-d#運算

print(e)

f=e/np.sum(e)#運算

print(f)

用python計算，#---------------------------------------------

import csv

csv_file =csv.reader(open('2.csv','r'))

print(csv_file)

for s in csv_file:

python科學計算與數據處理？print(s)

import numpy as np

print(csv_file)

np0= np.loadtxt(open("2.csv","rb"),delimiter=",",skiprows=0)#原始數據

np1=np0+0.0000001

Python 計算。print(np1)

a=np.sum(np1)

a=np.sum(np1,0)#列求和矩陣

print(a)

b=np1/a#運算

python應用案例。print(b)

c=b*np.log(b)#運算

print(c)

k=1/np.log(96)#注意，4方案數

print(k)

熵值法計算公式。d=-k*np.sum(c,0)#運算

print(d)

e=1-d#運算

print(e)

f=e/np.sum(e)#運算

python數學計算函數？print(f)

for i in f:

print(i)
