Second order Runge Kutta method

Solving ODEs in MATLAB, 3: Classical Runge-Kutta, ODE4

Runge-Kutta method (Order 4) for solving ODE using MATLAB

SOLVED:Use the fourth-order Runge-Kutta algorithm to approximate the solution to the initial value problem y^'=1-x y, y(1)=1 at x = 2. For a tolerance of e = 0.001, use a stopping procedure based on the absolute error.
