Web6 okt. 2014 · 1. A couple of things. First, you shoudl try to create a bigger data amount. 20 is a very low number to see any difference (but you will see it). Then, the problem is the data type. If you look at the variable called comp , the output of the Huffman encoding, it only contains 0s and 1s, is binary. However, in matlab, you are storing it as ... Web15 apr. 2024 · It seems that huffmandict does not like zero-probability symbols. It's creating extremely long codes (>100 bits), which causes the decoding to choke. The comments say that it huffmandict doesn't assign a codeword to zero-probability symbols, but it does.
