For a closer look at MATLAB and SIMULINK, type 'demo' at the MATLAB prompt.
Now type 'simulink' at the MATLAB prompt. The window which opens contains all the
blocks available for building simulation flowsheets. To create your own flowsheet, click
on 'File', then on 'New'. A blank window will appear. Double-clicking on any of the
icons in the simulink menu will open a submenu which contains useful blocks. Double
click on 'Linear', and drag a 'Transfer Fcn' (transfer function) block onto your new page.
Now from 'Sources', drag a clock and a step function into your new simulation window.
From 'Sinks', get two 'To Workspace' blocks. To connect blocks, click on the small arrow
from one block (the 'clock' for example), and hold the left mouse button down while you
drag the arrow to the port of another block ('To Workspace', for instance). You'll know
two blocks are connected when a large black arrow forms at the destination of the
connection. (See the figure below) To change parameters within a given icon,
double-click on that icon. A list of parameters will appear, and by clicking in the given
boxes and using the 'Backspace' key, you can change the parameter values.
Click on the 'Simulation' menu, and select 'Parameters'. In this menu you can change the integration scheme, simulation start and stop time, integration maximum and minimum step size, and the tolerance (for certain integration routines). To start a simulation, select 'Simulation' and 'Start'.
Take some time now to familiarize yourself with the MATLAB demo. To begin
the demo, type 'demo' at the matlab prompt.
