Why does NO ODE function work??

Hi,

I am about to mad - spent the entire evening trying to get matlab to solve ANY ode with the 'ode1' function.

It just says Unrecognized function or variable 'ode1'.

This is making me sick as I followed the so called 'cheif mathematician' from maths works on his tutorial on ODE1 - Euler's method - it DOES NOT WORK.

In fact, no ODE works....I am inputting the function as follows:

{F = @(x,y) x^2-3*y^2

x0 = 0;

h=1;

xend = 5;

y0 = 0;

ode1(F,x0,h,xend,y0)}
