You can't save anonymous function handles but you can load them and the
matlab V7.3 file format for saving 64bit files based on HDF5 is not
supported. Both of these would make a nice project for someone.

Don't include the line

#include <matrix.h>

in your mex files. Also the mex interface in octave imposes certain copying
of the data and so if you can accept that you code will be GPLed use the
oct-file interface instead.
