Solving second order inhomogeneous differential equations which are not a function of time

Hello Community!

Hoes does one solve a 2nd order ode of the form:

y′′+py′+qy=f(x)

Break the ode into two first order ode's.

e.g. dy/dx = v; dv/dx = f(x) - p*v - q*y;

Look up the documentation on ode45

Although the examples use t, for time, as the independent variable, this isn't necessary. You can use x , for distance, say, in its place.
