matlab code for huffman code

[adityabvmk]

can anybody please give the code for huffman coding in matlab....

Huffman Code is very easy..
MATLAB has an inbuilt code to get the Huffman coding, i.e. "Huffmanenco"
You can use it...Search fot this function in MATLAB and you will get the required details...

actually i want the code not the inbuilt function in matlab....thanks for reply

I think this will work.........

clc;
clear all;
close all;
sig=1:4;
Symbols=[1 2 3 4];
P=[0.1 0.3 0.4 0.2];
dict = huffmandict(Symbols,P);
temp=dict;
for i=1: length(temp)
    temp {i,2}= num2str(temp{i,2});
end
disp(temp);
hcode= huffmanenco(sig,dict)
dhsig= huffmandeco(hcode, dict)

that is ok...i want the background code for "huffmanenco" and "huffmandeco"....i think u got it now..

 

[errakeshpillai]

Thats okay...
I got it now....

can you please help me to do a huffman compression on a character string. For eg., i need to perform huffman compression on the statement 'This is an eg for huffman compression. This is a working algorithm. This has a significant compression ratio'. Thanks in advance....

I think this will work.........

clc;
clear all;

sig=1:4;
Symbols=[1 2 3 4];
P=[0.1 0.3 0.4 0.2];
dict = huffmandict(Symbols,P);
temp=dict;
for i=1: length(temp)
    temp {i,2}= num2str(temp{i,2});
end
disp(temp);
hcode= huffmanenco(sig,dict)
dhsig= huffmandeco(hcode, dict)
