Even, if I split the matrix into its real and imaginary part by

k0r = real(full(k00))
k0i = imag(full(k00))

and save them as two real matrices 

save -v4 -mat k0r
save -v4 -mat k0i

I obtain the same message as before


Traceback (most recent call last):
  File "matlab.py", line 4, in ?
    io.loadmat("k0r",appendmat=0)
  File "/usr/local/lib/python2.1/site-packages/scipy/io/mio.py", line
423, in loadmat
    raise ValueError, "Cannot handle sparse matrices, yet."
ValueError: Cannot handle sparse matrices, yet.

What is going on there ?
