What does the following code do?

clear all
close all
clc
x= input('Enter initial condition: ')
eps= input('Enter accuracy : ')
Nmax= 1e5
for N=1:Nmax
 f= 2*x+exp(x/pi)+sin(pi*x)-20
 df= 2+(1/pi)*exp(x/pi)+pi*cos(pi*x)
 newx= x-f/df
 if abs(newx-x)<=eps
 disp(['The solotion is: ',num2str(newx)])
 disp(['The number of attempts is: ',num2str(N)])
 break
 end
 x=newx
end
if N==Nmax
 disp('There is no solution for the given conditions!')
end

At least one END is missing. The statement beginning here does not have a matching end.

Talk to the source of the code Asing what uncommented junk code does is difficult to say, especially if we are given no clue as to what it is supposed to do. And, sorry, but this is junk code.

Please read this guide about how to ask a good question, and edit your question to improve it.

What your code will do is give the error message you see in red above (after I formatted your code, and ran it here).

Sorry I fixed the code
