Hi all,

I am reporting a bug in io.mmread.

mmread in Matlab can handle the input file.

The test file is attached

Traceback (most recent call last):
  File "benchmark.py", line 2, in ?
    f = io.mmread('windscreen.B.mtx.gz')
  File "/usr/lib/python2.3/site-packages/scipy/io/mmio.py", line 103, in 
mmread
    rows,cols,entries,rep,field,symm = mminfo(source)
  File "/usr/lib/python2.3/site-packages/scipy/io/mmio.py", line 65, in 
mminfo
    assert len(line)==2,`line`
AssertionError: ['22692', '1', '22692']

Nils
