Embedding using Genetic Algorithm

I'm doing a project on speech steganograpjy using GA. But I've no idea about how to do genetic algorithm in matlab.
For embedding I'm using Genetic Algorithm based embedding method. In MathWorks also I can't find any postings that tells us a basic structure of Genetic Algorithm, how to perform cross-over and mutation operations etc.

A small idea of what I want to do with matlab is as:
Ex. We have to embedd 31 in 1056
1056=0000010000100000
31=11111
Direct LSB replacement, = 0000010000111111(=1087, differs very much from 1056)
GA replacement, = 0000010000011111 (=1055, close to 1056),
Idea: Keep the lsb 5 bits(secret data -31) as such and change the remaining bits
so that the new changed value is closer to the original (1056 here). How to do this with GA?
