Hello, I want to have a program that can increase or decrease my time step as appropriate. The main program is: t = 0; %initialize time T = 2000; %Simulation Time in seconds del_t = 1 ; %arbitrarily chosen, as the program develops, we will get a better 1st estimate grid_size = 5; %assume the DEM has a resolution o... 25 May 2010 10:11

Using Embedded Matlab Function and Simulink Function on State-Flow with RTW
