RUNGE-KUTTA


Description

  • The Runge-Kutta method is a set of implicit and explicit iterative methods.
  • The most widely known method is RK4.
  • This function gives the approximate solutions to ordinary differential equations.

ZOS

RUNGEKUTTA(x0,y0,xn,n,f)

x0 - Initial value of x
y0 - Value of y at x0
xn - Value at which y has to be calculated
n - Number of intermediate values between x0 and xn.
step-length (h) = (xn-x0)/n
  • For example,

If we have f(x,y(x)) = (dy/dx) = 1-xy. Find y(1). where y(0) = 1 with one step
