[SciPy-user] Re: io.loadmat: broken?

[Yichun Wei]

Here is the file (I should have said that it is a .mat file saved using 
-v6 option of Matlab 7):

 >> a = 1; save -v6 a.mat a
 >> clear
 >> load a.mat
 >> a
a =
      1

The Enthought python with Scipy 0.3 loads this .mat file fine, however, 
it is not the case with Scipy 0.3.2:

 >>> a = io.loadmat('a')
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "C:\Python23\Lib\site-packages\scipy\io\mio.py", line 692, in 
loadmat
     thisdict = _loadv5(fid,basename)
   File "C:\Python23\Lib\site-packages\scipy\io\mio.py", line 631, in 
_loadv5
     el, varname = _get_element(fid)
   File "C:\Python23\Lib\site-packages\scipy\io\mio.py", line 619, in 
_get_elemen
t
     el, name = _parse_mimatrix(fid,numbytes)
   File "C:\Python23\Lib\site-packages\scipy\io\mio.py", line 510, in 
_parse_mima
trix
     result = squeeze(transpose(reshape(result,dims[::-1])))
TypeError: Array can not be safely cast to required type


 >>> import scipy
 >>> scipy.__version__
'0.3.2_280.4176'
 >>>
 >>> import Numeric
 >>> Numeric.__version__
'23.6'

I am not sure if this is brought by the new Numeric used here. This is 
on a Win2k. I am not sure if it is the case on other platforms.

Thanks for looking into this issue! I'm looking forward to use Scipy 
0.3.2 so as to be able to work with wxpython 2.5.x.x, pythoncard etc...
