I was wondering.. Is it possible to read a zipped file and calculate its entropy? I don't know how to read/open the zip file.. But I am familiar with the function Entropy.

fid = fopen('example.zip', 'r');
a = fread(fid);
fclose(fid);
H = entropy(a);

doc unzip
doc untar
doc gunzip
Probably one of these will help.

Nat's "Answer" to Sean moved here.
But I don't want to unzip the file. I just want to read it like that. something like:
a=readfile('example.zip');
H=entropy(a);
