I'm trying to help a user on the help mail list (Jarhead) who saved some data in matlab with the -v7.3 option which one would think would create a version 7.3 .mat file but instead it created an hdf5 file which fails to load
in his version of octave (it probably does not have hdf5 support), though it does load in mine (which does have hdf5 support). Has anyone heard of this behavior?
I thought about fixing load-save.cc to check for the hdf5 signature even
if it was built without hdf5 support so we could at least give the user a more meaningful error message.
