Why obtaining an error while displaying Runge kutta code

Hello,

While I run out the code for Runge_Kutta, an error appears as "not enough input arguments" in line 2.

1  function y=y(x)
2   y=sin(x)+2;
3   x0=0;
4   y0=1;
5   x1=4.5;
6   tol=0.02;

7  r=menue
......

what is menue?

The menu is for selecting the order of RK .

Don't run the function directly with run button.....call it using:

x = rand ;   % some input
y = y(x) ;

See to it that, you are in the folder where the function file is present.
