Fibonacci with discrete time models

We used the gvle.discrete-time package to model the [Fibonacci sequence] (http://en.wikipedia.org/wiki/Fibonacci_number) into the discrete-time extension (package vle.discrete-time)

Video comments:

• 0:00 : Create the package fibonacci and specify a dependency to the vle.discrete-time package.
• 0:18 : Create a new atomic model based on the discrete time formalism. By default, its name is NewCpp.
• 0:25 : Specify the equation F= F(-1) + F(-2) into the Compute section.
• 0:35 : Declare the variable F and the set an history size of 2.
• 0:45 : Set initial history F{n=-1}=0 and F{n=0}=1.
• 0:58 : Rename the atomic model to Fibonacci, configure and build the project.
• 1:19 : Open the default model empty.vpz and add an atomic model, configure it with the newly created dynamic Fibonacci from package fibonacci.
• 1:29 : Into the Observables tab, attach the observable port F to the available view of the vpz.
• 1:38 : Into the Project tab, specify the duration of the simulation to 6.
• 1:48 : Into the Simulation tab, launch simulation and select the variable F for plotting.
