# Example of how an LDPC code can be encoded using using sparse,
# dense, and mixed representations of the generator matrix. The dense
# and mixed representations are based on the same set of message bits
# as the sparse method with minprod heuristic. This allows the correctness
# of these methods to be checked by verifying that they all produce the same
# result when encoding random messages. The results are also checked by
# 'verify'.
#
# A (400,200) LDPC code with 3 checks per bit is used for the test.
set -e # Stop if an error occurs
set -v # Echo commands as they are read
