Changes in 1.5.3 (11 January 2016)
* Added support for writing numeric arrays to v4 MAT files
* Added Visual Studio project for test_mat
* Added new API functions Mat_CalcSingleSubscript2 and Mat_CalcSubscripts2 that
work on size_t type
* Fixed memory consumption reading compressed v5 MAT files
* Fixed bug writing compressed v5 MAT files
* Fixed bug in Mat_VarReadNextInfo5 where freed variable was not set to NULL
* Fixed several bugs in Mat_VarDelete
* Fixed bug writing empty struct to HDF5 MAT files
* Fixed bug writing character array to HDF5 MAT files
* Fixed bug writing character array to compressed v5 MAT files
* Updated Visual Studio solution and project files to work with newer HDF5 and
Visual Studio versions
* Various fixes for unused variables, unnecessary initializations, etc. that
cause compilers to issue diagnostics
* Several other fixes, especially for memory leak
Changes in 1.5.2 (31 July 2013)
* Added support for linear data read for v4 and HDF5 MAT files
* Fixed bug reading slices of variables in matdump
* Fixed feof calls so they compile on platforms that dereference the argument in
a macro
* More robust checking that file is MAT file and eliminates some segmentation
faults
* Various fixes for unused variables, unnecessary initializations, etc. that
cause compilers to issue diagnostics
* Several other fixes
Changes in 1.5.1 (10 March 2013)
* Fixed bug writing compressed HDF5 files
* Fixed bug reading cell array elements written with a non-empty variable name
* Fixed bug writing complex sparse matrices as struct fields or cell elements to
uncompressed v5 MAT files
* Fixed a number of potential issues identified via static analysis
* Fixed uninitialized pointers when creating structures through
Mat_VarCreateStruct, and fix a bug in the struct API testsuite
* Fixed extended sparse support in v7.3 MAT files and add 64-bit integer support
for v5 MAT files
* Added missing support for reading hyperslabs from HDF5 MAT files
* Added variable indexing notation support to matdump to display subsets of
variables
* Added tests for extended sparse support in testsuite
* Added missing enumerations or default case in switch statements
Changes in 1.5.0 (15 April 2012)
* Added support for reading/writing HDF5 format MAT files
* Bug fixes for compressed variables that caused issues with matio reading
them.
* Upgrade of dimensions in matvar_t structure to size_t enabling support for
large arrays.
* A testsuite
Changes in 1.3.2 (28 October 2006)
* Added support for writing compressed character classes, structures, cell arrays, and sparse arrays
* Added some tests to the test_mat program: write_compressed_cell, write_compressed_sparse
* Added 64-bit signed/unsigned integer support
* Fixed bugs in Reading slabs of N-dimensional data
Changes in 1.3.1 (7 September 2006)
* Added some internal documentation to the library
* Defined two documentation groups public and internal
* Disabled the building of test programs by default and added a configure
option to build them
* Fixed installation path of data and documentation
* Fixed bugs where file pointers were left open if allocating memory failed in Mat_Open and Mat_Create
Changes in 1.3.0 (30 June 2006)
* Cleaned out matio.h and made most preprocessor define's into enum's.
* Moved complex arrays from single pointer with real part followed by imaginary
part to a struct with a pointer to the real part and a pointer to the
imaginary part (Previous implementation was just plain ignorant).
* Changed version 4 mat file code from MAT_V4 to MAT_FT_MAT4 to match the
version 5 identifier.
* Added function Mat_VarCalloc to allocate and initialize all fields of the
matvar_t structure.
Bug Fixes in 1.3.0 (30 June 2006)
* WriteCompressedData did not initialize the data tag (data_tag variable).
* WriteStructField wrote the array name tag as a 2 byte integer followed by 2
padding bytes. Correct implementation writes the array name tag as a 4 byte
integer.
* Write5 wrote the array name tag as a 2 byte integer followed by 2
padding bytes when the name was more than 4 characters. Correct
implementation writes the array name tag as a 4 byte integer.
* Write5 had a hard-coded uncompressed variable size of 448 when writing
compressed data.
* WriteInfo5 wrote the array name tag as a 2 byte integer followed by 2
padding bytes when the name was more than 4 characters. Correct
implementation writes the array name tag as a 4 byte integer.
* Mat_Create wrote the endian sequence incorrectly.
* Mat_VarCreate set the number of bytes incorrectly for structures.
* Mat_VarCreate fixed the data size of the character class to 1. That didn't
allow for multi-byte characters.
Changes in 1.1.6 (20 March 2006)
* Added sparse class to compressed variable.
Bug Fixes in 1.1.6 (20 March 2006)
* Fixed release bug in reading double class data.
* Fixed various compressed variable writing bugs.
* Fixed a bug in Mat_VarCreate for sparse variables.
Changes in 1.1.4 (9 February 2006)
* Changed Licensing from the GNU General Public License to the GNU Lesser
General Public License.
* Added support for reading numeric version 4 MAT files
* Added support for sparse datatypes other than double. Although Matlab does
not support these types, other free software does.
* Writing compressed variables is supported for Numeric arrays. Future versions
will implement character, sparse, cell, and structure arrays.
* A Fortran 90/95 interface has been incorporated. Not all functions are
implemented yet, but more will come and it is at least functional now.
Hopefully feedback will help guide the Fortran interface development.
* Replaced preprocessor defines for types,classes,etc. with enum's.
Bug Fixes in 1.1.4 (9 January 2006)
* Mat_VarReadData did not handle complex data
