A couple different ways, depending on what you want to do. If you simply want to combine the functionality of existing blocks into a new block, you can simply create a subsystem of those blocks, and then mask it - in this way, your subsystem (i.e. your block) can have any number of inputs and outputs. Alternately, if you want to write a new block from scratch, you can do so as a m-file or c-mex- file s-function (there is a good deal of information on this in the s- functions manual - it is in the simulink directory of the online documentation) - it is not too difficult to have multiple inputs or outputs here, either. Again, to give them the appearance of a block you should mask them. Having created these blocks, you may create a new library to hold them, or add them to an existing library. Information on creating a new library (under Matlab R11) is available at the Mathworks website at http://www.mathworks.com/support/solutions/v5/9009.shtml Hope this can be of some help to you.
