      At the first step, the first half of the left side in Equ. 1 and the first half of the left side in Equ. 2 are treated as implicit. We plug Equ. 2 back to Equ. 1 and obtain Equ. 3. Equ. 3 can be easily solved with a tri-diagonal matrix solver. This procedure is conducted for all three components of the electric field.

To illustrate, consider the simplified equations for Figure 8-31 of Example 8-14. These equations are found at the end of Step 6 and are. 0.075 V1 ( 0.025 V2 = 250 mA (11a) ( 0.025V1 + 0.0583 V2 = 150 mA (11b)

      After running the simulation for 40 time units, the command was issued in the Command Window to generate the plot of the step response shown in Figure 4. Notice that the plot is not as smooth as the one obtained from the “step” command. This is because the SIMULINK solver used a coarse grid of points to compute the solution.
