How do call the function when you get that error?

>> x = myfuction( )
Not enough input arguments.
Error in myfuction (line 3)
    N = size(A,1); 
3       N = size(A,1);

Are you just clicking the green Run triangle without ever actually calling the function and passing variables into it like per did? That would cause an error. You MUST pass it variables!
