Question

How can I rewrite and better understand the code since it is not working. Thank you for helping me!! It means a lot :)

CODE:

import numpy as np

def coeff(x):

X = x[:,0]

Y = x[:,1]

  

if len(X)>=11:

L = 10

else:

L = len(X)-1

  

nm = np.zeros((L,1))

  

for i in range(1,L):

fit = np.polyfit(X,Y,i)

val = np.polyval(fit,X)

nm[i-1,0] = np.linalg.norm(Y-val)

  

I = nm.argmin()

coeff = np.polyfit(X,Y,I)

print(coeff)

Answer 1

I made a small modification in the program and got that as output. Is it the thing that you what otherwise you can specify the requirements so that I will modify according to that.

If you have any doubts please comment and please don't dislike.

import numpy as np

def coeff(x):
   #selecting the 0th array and elements in it
   X = x[0,:]
   #selecting array at index 1 and elements in it
   Y = x[1,:]
   print(X)
   print(Y)
   if len(X)>=11:
       L = 10
   else:
       L = len(X)-1
   nm = np.zeros((L,1))
   print(nm)
  
   for i in range(1,L):
       fit = np.polyfit(X,Y,i)
       val = np.polyval(fit,X)
       nm[i-1,0] = np.linalg.norm(Y-val)
       I = nm.argmin()
       coeff = np.polyfit(X,Y,I)
       print(coeff)
coeff(np.array([[1,2,3,4,5,6,7,8,9,10,11],[1,2,3,4,5,6,7,8,9,10,11]]))
