Minimization of many-variable function

[gaby287]

Hi, I'm learning python and I'm just trying to minimize a function of many variables, but I have some problems with my code.

import numpy as np
import scipy.optimize as op
from scipy.optimize import minimize

table1_np = np.genfromtxt('Data/tabla1.txt', usecols=0)
#--------------------------
def function(r0, rs):
      r0, rs = parameters
     return (r0*rs**3/table1_np[I])
def function2(parameters):
      return sum(table2_np[I] - function[I])
           x0=np.array[0.7, 1.1]
      res=minimize(function2, x0, method = 'nelder-mead', options={'xtol':1e-8, 'disp':True})

Perhaps you could tell us more about the function you want to minimize and the steps you need to take to do it.

I have some problems with my code

What are the symptoms of those problems?

Well I have a table of data (table1_np) and I want to use it to define a function, but the problem is, that I don't know if the definiton is correct, because what I need to do sum the elements of other table whit that function and after that minimize the result.

There are some NameErrors in the code as you've likely seen. The tuple 'parameters' I believe you intend to be passed into the first function as it is the second function. Also the index name 'I', 'table2', etc.
