ONE DIMENSIONAL SYSTEMS, PARTIAL DIFFERENTIAL EQUATIONS
Solution of the heat equation for a thin bar with insulated sides
- Using finite-difference method: HeatedBar0.m
- Using separation of variables (Fourier series): HeatedBar3.m
Reflected waves on a transmission line. TLreflections.m simulates multiple reflections of a rising edge or a pulse. Rise time is variable, relative to the length of the line, so that the transition from distributed to lumped behavior can be observed.
