% DDECOMPRESS - decompress DZIP output to recover original data
%
%
% VARIABLES:
% Z = compressed variable to decompress
% M = decompressed output
%
% NOTES: (1) The input variable Z is created by the DZIP function and
%            is a vector of type uint8
%        (2) The decompressed output will have the same data type and
%            dimensions as the original data provided to DZIP.
%        (3) See DZIP for other notes.

function M = ddecompress(Z,op)

  import com.mathworks.mlwidgets.io.InterruptibleStreamCopier

  a=java.io.ByteArrayInputStream(Z);
  b=java.util.zip.InflaterInputStream(a);

  isc = InterruptibleStreamCopier.getInterruptibleStreamCopier;
  c = java.io.ByteArrayOutputStream;
  isc.copyStream(b,c);
