How Huffman Key is getting generated in this?
Is this?
function [key] = keyGen(n)
n = n*8;
bin_x = zeros(n,1,'uint8');
r = 3.9999998;
bin_x_N_Minus_1 = 0.300001;
x_N = 0;
for ind = 2 : n
x_N = 1 - 2* bin_x_N_Minus_1 * bin_x_N_Minus_1;
if (x_N > 0.0)
bin_x(ind-1) = 1;
end
bin_x_N_Minus_1 = x_N;
end
t = uint8(0);
key = zeros(n/8,1,'uint8');
for ind1 = 1 : n/8
for ind2 = 1 : 8
key(ind1) = key(ind1) + bin_x(ind2*ind1)* 2 ^ (ind2-1);
end
end
Command Window: or call the function from other matlab Main Script
>> b=keyGen(10)
b =
10×1 uint8 column vector
