The primitives and modules collected in this library where developed by Karim Khiar from Thomson CSF. They are used by a demonstration named RadarChainProcessing which can be found in MLD Libraries→HOF Domain→Demo. The radar simulation, though five-dimensional, is implemented using SDF, which is a one-dimensional data flow model.
Most of the primitives that interface to Tcl appear in libraries that reflect their function. For instance, all the primitives beginning with Tk in the sinks library are actually Tcl primitives derived from TclScript. This is the most generic Tcl primitive with no function on its own. It must have a Tcl script associated with it to make it useful. Please refer to
Programming→Using Tcl/Tk in primitives
to learn about writing such scripts.
