% Decompressing an Zstd-compressed byte-stream to recover the original data
% This function depends on the ZMat toolbox (http://github.com/NeuroJSON/zmat)

%
% input:
% input: a string, int8/uint8 vector or numerical array to store Zstd-compressed data
% info (optional): a struct produced by the zmat/zstdencode 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]=zstdencode(eye(10));
% orig=zstddecode(bytes,info);
