I am currently looking for density evolution (sum product, belief propagation or message passing decoding) of LDPC code on mathwork but most of the result is just differential evolution. Any recomended idea for an efficient implementation of this algorithm ?

Different matlab implementation of Density Evolution for optimizing LDPC codes degree distribution under AWGN you can get from https://github.com/Lcrypto/Density-Evolution-AWGN . For same task using exit-chart, protograph pexit-chart and optimization under Fading channel you can get as well in different repo https://github.com/Lcrypto/ BR, USA_UK
