Please solve with Matlab and please Pseudocode :)

Solve the initial-value problem x' - x/t sec(x/t) with x(0)0 by the fourth- order Runge-Kutta method. Continue the solution to t = 1 using step size h = 2-7. Compare the numerical solution with the exact solution, which is x(t) = t arcsin. Define?f(0, 0) 0, where "f(t, x)-x/1 + t sec(x/1)
