Compiler and shared C library

Hi all,
I am trying to understand how to use the Compiler toolbox to distribute a shared C library. What I currently have in MATLAB is 5 functions, each in its own .m file, and each one can be run essentially as a standalone. That is, you call one of the functions, pass some arguments, it runs for a few minutes and returns some values. I also have a separate directory in the MATLAB path that contains all sorts of functions that I am calling from my 5 main functions. I will refer to this as the '.m library folder'. Some of these I created myself, some I downloaded from FEX. What I want to do is generate each of the 5 functions as a separate C shared library, so that each can be called separately from C. How do I go about doing this? Do I create 5 separate projects in the Compiler toolbox? Do I include the .m library folder with each project or can I compile each of those files separately and link them later?

Thanks Walter. I have to think about this. Another problem I am having is in finding clear and concise documentation for the C programmer on how he can integrate the compiled matlab shared libraries in his C code. He has no knowledge or experience with MATLAB. I downloaded the Compiler toolbox pdf documentation here http://www.mathworks.com/help/pdf_doc/compiler/compiler.pdf but its so disorganized. And it sends you to different documents for various things. For example, it doesn't cover MATLAB data types and their C equivalent.. it refers you to the External Interface document (<http://www.mathworks.com/help/pdf_doc/matlab/apiext.pdf>) under the MEX chapter to learn about data types. And other documents for the MCR API. It's so just confusing and hard to follow. Do you know if there is something written that details everything he has to know in one place? Thanks!
