22 May 2008	Mostafa Afgani	Excellent set of tools. I was looking for a straight-forward way to extract partial datasets from a HDF5 file and this was perfect for that.
08 Jul 2008	Anthony Kendall	Works exactly as it should. This mimics the higher-level MATLAB HDF5 functions in terms of simplicity, but gives access to lower-level functionality. Great!
14 Jan 2010	Joao

26 Mar 2011	Piers	Very handy tools. It took a while to figure out that 'chunk_size' is needed to set 'max_size' for h5datacreate. I needed to set the fill value, so I added that option. Also there is a small bug in 'max_size', inf isn't handled correctly. see http://www.toverlamp.org/static/h5datacreate.m and incorporate changes if you want.
14 Jun 2011	Curtis Gehman	Basically what I was looking for. The help should indicate what happens when the read or write operations fail. A function to simply get the size and type of a data set would be handy.

Updates
26 Oct 2007	Added H5VARPUT. Added example for H5VARGET.
29 Oct 2007	Two additional function, H5ATTGET and H5ATTPUT
30 Oct 2007	Added read support for references in H5VARGET. References now look the same as what the low-level interface expects. Refactored H5ATTPUT, H5DUMP. Got rid of mlint warnings. Prints a placeholder for compound attributes in H5DUMP.
05 Nov 2007	Fix to compensate for enum byte swapping issue. Added preference for full enumeration support.
05 Jan 2009	Added new H5PROPINFO m-file. Some error checking changes. Fixed int64 bug on H5ATTPUT on 32-bit platforms.
11 Jan 2009	Added int16 enum support, NaN support for fillvalues in double, single precision datasets. Fixed invalid fieldname issue in H5PROPINFO.
26 Jan 2009	Rewrite of H5DUMP. Added H5IMREAD, H5IMFINFO functions.
08 Feb 2009	Adjusted expected values for H5PROPINFO for the correct HDF5 library version. Minor fixes to H5DUMP.
19 Feb 2009	Updated H5PROPINFO for new properties. Removed garbage version of H5DUMP. Fixed several testing issues.
08 Mar 2009	Fixed bug in fill value handling for H5VARGET and H5VARPUT. Added support for bit field datatypes in H5DUMP.
12 May 2009	fixed h5varput bug, 'H5S_ALL' is not appropriate for partial writes
27 May 2009	Credits The HDF Group for some of the test files.
27 Jul 2009	Bounds selection fix in H5VARGET, test suite fix. Thanks to Jon Olav for finding this.
07 Oct 2009	Updated H5DUMP for R2009b
15 Oct 2009	Allowing for 2D char attributes. Fixed typo for H5DUMP and clearly stated release requirements. Removed 3-argument signature for H5ATTPUT.
21 Jun 2010	Added two new functions suggested by customer. Optimized H5VARGET with better choice of H5D.read parameters.
