# 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
