MATLAB MEX functions for encoding/decoding of RS codes

This submission includes 2 MATLAB MEX functions, rsenc_mex and rsdec_mex, that do RS (Reed-Solomon) encoding/decoding by calling the RS encoding/decoding functions implemented in C by Simon Rockliff. I hope it's helpful for those who want to do simulations related to RS codes in MATLAB.

rsenc_mex and rsdec_mex functions work much faster than the old MATLAB rsenc and rsdec functions. (However, it is expected to be no faster than the new MATLAB communication toolbox RS encoding/decoding functions, i.e., comm.RSEncoder, comm.RSDecoder, since efficiency is not born in mind during implementation.)

Please follow the instructions in readme.txt to 1) compile and 2) test the codes.

Thanks Simon Rockliff again for providing such a perfect C implementation! For more implemented coding algorithms, you may want to check "The Error Correcting Codes (ECC) Page": http://www.eccpage.com/
