Changes in 1.5.0 (15 April 2012)
* 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 Septempber 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 preproccessor 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
