[c,d]=crossover(a,b)
Data of crossover.m file is as under % Crossover operator
function [c,d]=crossover(a,b)
nn=length(a)-1;
% generating a random crossover point
cpoint=floor(nn*rand)+1;
c=[a(1:cpoint) b(cpoint+1:end)];
d=[b(1:cpoint) a(cpoint+1:end)];
end
% end for crossover
when i run the program i get this in return from command prompt "Error: File: GA.m Line: 169 Column: 2 This statement is not inside any function. (It follows the END that terminates the definition of the function "bintodec".)"
Please tell where the problem

Bilal Khurshid you are calling the functions crossover and mutate, after the end of function GA.m. You cannot call a functions after ending a function. You can write the definition of the functions after end of main function, but you cannot call it. Change the location of those two functions; place them where you want to call/use them. In the attached code, I have changed their position, that error is not showing out now.

Thanks Dr Silva i have replaced my GA.m file with your modified file, but still i am getting this error
>> [costs,schedule]=GA([2 3 1 4],2,12) Undefined function or variable 'pm'.
Error in mutation (line 5) if pm>rand,
Error in GA (line 93) [kk,popnew]=mutation(popsize*rand);

This is a error in your function mutation...you have used pm inside it and it is not sent/ defined inside the function.

I have added valve of pm and random operator is mutation function file, but still getting following error
Error in mutation (line 4) pm=0.05; % Mutation probability
Output argument "kk" (and maybe others) not assigned during call to "C:\Users\Bilal\Desktop\GA test\mutation.m>mutation".
Error in GA (line 93) [kk,popnew]=mutation(popsize*rand);
