C++ class to write HDF5 .mat files.
This is a small C++ class that lets you write matrices, vectors and values to a .mat file. It is simple enough that you can easily modify it yourself.
The mat file format is simply an HDF5 file with a pointless header prepended. This class uses libhdf5 from here:
http://www.hdfgroup.org/HDF5/release/obtain5.html
to write the HDF5 file, and the prepends the header to it. Currently it reads the entire file back in and writes it all out again with the header, because I couldn't get the HDF5 library to append to an existing file. If anyone knows how I'd love to know!
The resulting files can be loaded in matlab using
load('/path/to/file.mat'); % Puts contents in main workspace.
s = load('/path/to/file.mat'); % Puts contents in s structure.
