Upconverter & Receiver Spurious Analysis using MatLab

I heard and had seen Spurious Analysis result of microwave upconverter and receiver using MatLab Simulink. It is able to model the filters, amplfier and mixer behaviour. It seems to be graphical driven based design, rather than writing long MatLab code. I must admit I know very minimum about MatLab.

Could someone post a simple example or explain how this is done?

Thanks

To be glib, it's done by defining Simulink blocks with the desired input/output characteristics, and then hooking them up. There is an RF toolbox from Matlab that may make this a little easier to do. If you go to http://www.mathworks.com/products/rfblockset/ they have some documentation on this.

I'd say that it's probably a little easier to do this in simulink than in matlab, but there is probably some existing matlab code on the net to do some of this.
