2. Scicos editor

In Scicos, systems are modeled by interconnecting blocks and subsystems (Super blocks); blocks can be found in various palettes or be defined by user. Scicos has an easy to use graphical user interface for editing diagrams. To start the editor, in Scilab, type scicos();. This opens up Scicos' main window.

Construction of Scicos model typically consists of

• opening one or more palettes (using Palettes button in the Edit menu),
• copying blocks from palettes into Scicos' main window; this can be done by selecting the copy button in the Edit menu, then clicking on the block to be copied, and finally in the Scicos' main window, where the block is to be placed.
• connecting the input and output ports of the blocks by selecting first the link button in the Edit menu, then clicking on the output port and then on the input port (or intermediary points before that).

Note that to make a link originate from another link (to split a link), user should first click on the Link button and then on an existing link, where split is to be placed, and finally on an input port (or intermediary points before that). The process of link creation can be stopped and current link deleted by clicking on the right mouse button.

Note also that at least one scope or a ``write to file'' block should be placed in any Scicos diagram to visualize or save the result of the simulation. See Scicos demos for examples.
