NAME

       Barcode::DataMatrix::Reed - Renamed version of Algorithm::DataMatrix::Reed

DESCRIPTION

       This is just a renamed version of Algorithm::DataMatrix::Reed by Mons Anderson from
       http://code.google.com/p/perl-ex/

       For a rough explanation of the structure of this code, see
       <https://en.wikiversity.org/wiki/Reed%E2%80%93Solomon_codes_for_coders#Reed.E2.80.93Solomon_codes>.
       Note that the link is not the basis of the implementation (this is unknown), however it
       helps explain how Reed-Solomon encoding is implemented and hence how the code below works.

   DEBUG
       Control whether or not debugging output is printed.

   mult (x, y)
       Multiply two Galois field element values and return the result.

   encode (ai, j)
       Encode the message array and return it.
