ccdf

 I find an example for ccdf command in mathworks website tutorial. But I am getting error when i run it in my system.
I am using the version MATLAB 7.7 (2008 b). Does this version supports the command ccdf (complementary cumulative distributive function).

It is a class that is part of the Communications Toolbox; http://www.mathworks.com/help/toolbox/comm/ref/comm.ccdfclass.html

Unfortunately, I am having difficulties in contacting the Mathworks pages this evening, so for now I cannot trace back to find out when it was introduced.
