Matlab class to losslessly compress and uncompress numerical matrices and strings in memory
d = randi(8,1000,1000); % generate some data
M = mkzip(d) % returns compressed version of d in mkzip object M
d = M.unzip; % returns uncompressed data in d
r = M.ratio % returns the compression ratio r
This is a class wrapper for Michael Kleder dzip/dunzip functions. The main advantage of making this a class is that it is impossible to forget that a certain array is zipped and end up doing calculations on it as if it is the actual data, which could be disastrous. It also provides some extra functionality (e.g., ratio) and as a class only one M-file is needed instead of one for dzip and one for dunzip.
