... What are you trying to do? And where is the problem? You have a lot of functions in there - which is giving you the issue?

[Mohammad]

this is tic tac toe game . can u run this project in your computer??

Answer 1

[Brian B]

You need to call this function with an input argument, as in:

 sumcheck(1)

Of course, this is just an example. I have no idea (because I didn't read the rest of the code) what kind of argument it expects.

[Mohammad]

plz copy of this code in your mathlab and tell me where the problem is please

[Brian B]

Sorry; I'm willing to help you understand problems you find. I won't debug it for you.

We've already pointed out the cause of the error you describe: this code is a function, not a script. So you need to call it with arguments, as I wrote above.

Did you try that? What happened? What should have happened? Do you know what input you ought to give?

Answer 2

[Walter Roberson]

You cannot run those routines by pressing F5 or clicking on "run" in the menus. Instead, at the command line, you must type in

check(t)

where t is the matrix of values you want to run the program with, such as

check([11 48 153234 83 17])

[Mohammad]

sorry but i cont underestand what did you say. can u explain more

[Walter Roberson]

Exactly how are you running your code at present?
