Very good but the way 'c' grows inside the loop makes it run slow for large runs.

Adding 'c = zeros(outputs,n);' right after the first line defining 'n=length(s)' made this this run 25x faster in my case.

Very useful and easy to use for generating Pseudo random binary sequence.


Updating description of the faster ones


Including 3 versions, LSFRv3.m is faster, solving the issue of maximum recursion error

Now code include better explanation with example in it

Now LFSR is available as toolbox, in addition m file includes instruction to use it as well as more friendly to give you option to avoid verification process
