def runge_kutta(func, x0, y0, x, h=0.5): | |
# count number of interation using step size or | |
# step height h | |
n = int((x-x0)/h) | |
# iterate for number of iterations | |
y = y0 | |
for i in range(1, n+1): | |
# Apply runge-kutta formula to find the value of y | |
k1 = h * func(x0, y) | |
k2 = h * func(x0 + 0.5*h, y + 0.5*k1) | |
k3 = h * func(x0 + 0.5*h, y + 0.5*k2) | |
k4 = func(x0 + h, y + h*k3) | |
y = y + h*(k1 + 2*k2 + 2*k3 + k4)/6 | |
x0 = x0 + h | |
# return y, the result | |
return y |
