Unable to load matlab-produced mat files in octave

[George Kousiouris]

Hi all,

I have a neural network created with Matlab 7.5 and stored in a mat file.
I am trying to load it to Octave 3.0.1 unsuccessfully. I have also tried
saving it as older Matlab version, however with the older versions I get
the error

Unknown object.

Saving it as 7.3 version, I get the following error when attempting to
load it in Octave:

error:load:error while reading hdf5 item IW


Any suggestions?

Thanks in advance and best regards,
George
