09 Nov 2009 Compute hash using MD2, MD5, SHA-1, SHA-256, SHA-384, or SHA-512 Hashes a string (or other MATLAB variable) using a vairiety of hash algorithms Author: Michael Kleder Danila

26 Oct 2009 Rapid lossless data compression of numerical or string variables Rapidly compresses (or decompresses) Matlab variables in memory Author: Michael Kleder Hopkins, Jesse

Needed to make the following changes to eliminate above java exceptions (in R2008b)

dzip.m line 48: change "DeflaterOutputStream" to "GZIPOutputStream"

dunzip.m line 21: change "InflaterInputStream" to "GZIPInputStream"
21 Oct 2009 Rapid lossless data compression of numerical or string variables Rapidly compresses (or decompresses) Matlab variables in memory Author: Michael Kleder Hopkins, Jesse

Using R2008b an exception occurs at line 24 of dunzip:
??? Java exception occurred:
java.util.zip.ZipException: unknown compression method

at java.util.zip.InflaterInputStream.read(Unknown Source)

at java.io.FilterInputStream.read(Unknown Source)

Any thoughts on what needs to be changed?
20 Oct 2009 Compute hash using MD2, MD5, SHA-1, SHA-256, SHA-384, or SHA-512 Hashes a string (or other MATLAB variable) using a vairiety of hash algorithms Author: Michael Kleder Simon, Jan

Works correctly, good help, no H1-line, example, date and author mentioned in the source.

~any(strcmp(meth, algs))
  is faster than:
isempty(strmatch(meth,algs,'exact'))

The conversion of the HEX output is to complicated:
  h=typecast(x.digest,'uint8');
  h=dec2hex(h)';
  if(size(h,1))==1
     h=[repmat('0',[1 size(h,2)]);h];
  end
  h=lower(h(:)');
Easier and faster:
  h = sprintf('%.2x', typecast(x.digest, 'uint8'));
For Matlab 6.5: only MD5 and SHA-1 are working, TYPECAST must be downloaded from FEX, and the SPRINTF needs a cast to DOUBLE.

Because you call Java for the calculation, this is not very fast, but still the most reliable hash tool in the FEX. Thanks!
