# Barcode::DataMatrix::Reed(3pm)

Renamed version of Algorithm::DataMatrix::Reed

## 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.
