Split the signal S(SPACE,TIME) into its downward/upward space propagating and stationnary components via a 2D Fourier decomposition. S is a (SPACE,TIME) matrix. We eventually proceed to a space and/or time filtering. DT,DX are temporal and space step. PERIOD=[Tmin Tmax] and WAVELENGTH=[Xmin Xmax]...

This example using Matlab commands to access Simulink Signal properties to easily create a batch file that can log almost any Simulink signals. This is very useful for batch testing when the parameters in the Simulink model are set in a m-file. It helps to reduce the use of Save-To-Workspace blocks.
