ODE Runge Kutta MATLAB error

Question

so I\'m trying to create a Runge Kutta function and this is my code :

function [t,U] = RK(f, n, eta, interv)
h = (interv(2)-interv(1))/n;
t = interv(1):h:in         


        

Answer 1

You are using the sin as a function handle. Just add the @ symbol and you're set.

RK(@sin, 10, [0,1], [5,15])
