software to find the threshold of an LDPC code in a Gaussian channel

This package contains software to find the threshold of an LDPC code in a 
Gaussian channel using the Fast Enough Evolution of Densities (FEED) 
algorithm.  FEED is based on the approach of Jin and Richardson's Fast
Density Evolution, but non-negative least squares is used to implement
the inverse Laplace transform, instead of the method they proposed.

For a quick start, and to understand the meaning of the parameters,
execute the script "feed_script.m".
