The algorithm made in c ++ is shown below so that you can develop it in matlab.
A code for the detection and correction of errors was implemented using the Hamming method, this code was made in c ++. Make the code in Matlab, in such a way that the c ++ code is a base, to be able to develop the

Note: I had already published it before, however it does not do the same functions, and what we want is for it to be the same as in c ++, but to be able to work with it in matlab.
note2: It is to replicate the same c ++ code in matlab.
