This is an example from new book "MATLAB and Simulink" by Bogumila and Zbigniew Mrozek. A problem was how to provide additional parameter "beta" to ODE23 solver, as it uses user supplied function xdot=mech_ode(t,x) with two input parameters.
In "oscillator.m" , a nested functions was used to provide actual value of "beta" parameter into function xdot=mech_ode(t,x). Global variables are not used here.
See also: "APP based on nested function, graphical user interface (GUI)
and GUIDE tool" by Zbigniew MROZEK. It is an example showing how to use this example to prepare an APP (MATLAB application) using MATLAB 2012a or higher.
