Example - Time Varying Continuous Transfer
Function
The stvctf S-function is an example of a time varying continuous transfer
function. It demonstrates how to work with the solvers so that the simulation
maintains consistency, which means that block maintains smooth and
consistent signals for the integrators despite the fact that the equations that
are being integrated are changing.
