Lesson 4: LR Circuit and Variable Time Steps

The objective of this lesson is to use Matlab to model an LR circuit. Variable time steps are needed in many problems where the solution changes from almost linear curves (can use larger time steps) to curves with larger curvatures (need to use smaller time steps).

In lessons 5 and 6 we will introduce higher order methods. And in lesson 7 we will start to use a Matlab application called ode45, which uses a combination of variable time steps and higher order methods.
