Are you sure?? as far as I know there is no predefined function "awgn" in matlab, though you can make it preety easily. Which awgn you are talking about, is it the basic model for a digital communication channel? for that you can easily use inbuilt gauss noise model with autocorrelation function and weighted delta function. Its a simple noise addition model and can be built easily, but there are no inbuit functions like "awgn" in the matlab (at least up to matlab version 7.1). You may try the matlab help forums of Mathworks or kluid [ http://www.kluid.com ].
