| Octave will not open a mat file saved using scipy.io.savemat. I believe

| The Matlab (TM) file readers/writers have a number of improvements:

| * default version 5
| * v5 writers for structures, cell arrays, and objects
| * v5 readers/writers for function handles and 64-bit integers
| * new struct_as_record keyword argument to ``loadmat``, which loads
|   struct arrays in matlab as record arrays in numpy
| * string arrays have ``dtype='U...'`` instead of ``dtype=object``
| 
| The error I get when opening the attached file is:

Instead of sending a scipy script, how about sending a (small) .mat
file created by scipy that shows the problem?
