| Communications Blockset Release Notes | |
New Block Libraries in Release 12
The Communications Blockset uses a new set of block libraries, although it also includes the previous set of block libraries for backwards compatibility. The new set of libraries is what appears in the Simulink Browser (on PC) and what opens if you type commlib at the MATLAB prompt. You should build new models using this new set. New blocks in the new set of libraries are described in New Features.
Your previous models link to the previous set of libraries unless you choose to replace individual blocks manually. You can access the previous set of libraries by typing commlib 1.5 at the MATLAB prompt.
