How do you want the output files to be formatted? Binary data? Textual
representation?
This function can do both:
http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.tofile.html
And numpy supports a variety of methods for outputting to files (and
reading data back in):

You can save them to separate fi
Is there a way to convert an array to string elements in numpy,
without knowing the string length?
>>> arr2 = np.arange(8, 13)
>>> arr2.astype(str) # bad
array(['8', '9', '1', '1', '1'],
dtype='|S1')
>>> arr2.astype('S2')
array(['8', '9', '10', '11', '12'],
dtype='|S2')
>>> map(s

I use up-to-date Debian testing (wheezy), amd64 architecture.
From the docs for numpy.MachAr:
maxexp int Smallest (positive) power of ibeta that causes overflow.
On my machine, ibeta = 2 and maxexp = 16384.
For float64, float32, and float16 things behave as expected. For float128,
I get the m

Not really. In the next release of NumPy you should be able to do.
result = array(arr2, str)
and it will determine the length of the
