%
% input:
%      input: a string, int8/uint8 vector or numerical array to store Lzip-compressed data
%      info (optional): a struct produced by the zmat/lzipencode function during 
%            compression; if not given, the inputs/outputs will be treated as a
%            1-D vector
%
% output:
%      output: the decompressed byte stream stored in a uint8 vector; if info is 
%            given, output will restore the original data's type and dimensions
%
% examples:
%      [bytes, info]=lzipencode(eye(10));
%      orig=lzipdecode(bytes,info);
