File test.m is an example of usage. It performs both Fountain and Raptor codes. For the former, flag LTFlag controls Fountain implementation between LT Fountain (according to Lubi’s paper) and windowed random Matrix Fountain (according to Ian Blake paper). For the latter, Reed-Solomon outer code is used, which is ideal for erasure channel. No need for communication toolbox if not using Raptor.
File ReadMe.pdf includes additional notes.

Dear Sir, I think your G matrix has some problem. I see that G matrix of Raptor is simple than G matrix of LT code. In the raptor code, they use shokrollahi distribution. Is it correct?
