Optimisation using scipy

Question

In the following script:

import numpy as np
from scipy.optimize import minimise

a=np.array(range(4))
b=np.array(range(4,8))

def sm(x,a,b):
      sm=np.zer         


        

Answer 1

Modifying the proposal of FuzzyDuck, I replace sm +=((b-a)**2) which return me the desired result.
