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
......

请先登录，再回答此问题。

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.
