Description:
The program 'bch_matrix' generates the G and H matrix of arbitrary BCH
codes in systematic form. A good introduction to the used coding
algebra is given in the book S.Lin/D.Costello "Error Control Coding".
The command line options of the tools can be displayed with -h !

Example:
>bch_matrix -n 7 -k 4 -p 1011
g(x) = x3 + x1 + x0
1011
h(x) = x4 + x2 + x1 + x0
10111
r(x) = null vector
