[dhvani patel]

can anyone plzzz rectify n solve the error...

[Giorgos Papakonstantinou]

Seriously dhvani how is it possible someone to help you when you 400 lines of code.

1. You have posted 400 lines of code without formatting it. It makes it impossible to read. Use the code button please to format your code.
2. The .m file that you have posted is accompanied by a figure which is missing. It makes it impossible to run you .m file.
3. Most important you have not even explained the error. You could have appended only a snippet of your code explaining what is the problem.

Please consider making these changes.

[Andrew Newell]

I have formatted the code for you, but please do it yourself next time.

[Giorgos Papakonstantinou]

At line 115 you say:

% handles.N=N;

Uncomment this line. However, I cannot guarantee that your code will work.
