File Information
Description

This submission is an example showing how a Level 2 M-file S-function can be used to help debugging models and vizualize the values computed by the SimulinkĀ® solver at minor time steps.

This submission contains a Level-2 M-file S-function that logs the minor time step data of a signal into the MATLABĀ® workspace and displays it in a figure at the end of the simulation.

The block is in a library and includes an slblocks.m file. Just place it on your MATLAB path and you should see it appear in the Simulink Library Browser. One example model is also included to demonstrate typical usage.

Required Products Simulink
MATLAB release MATLAB 7.8 (R2009a)
