Easiest or best?

In the next release I've added load and save funcs for converting
arrays to and from ascii files.  But this is slow and generally lossy.

Best is to use the binary string operations tostring and fromstring

    from Numeric import fromstring, Float
    # write
    file('fname.out', 'wb').write(x.tostring())

    # read
    x = fromstring(file('fname.out', 'rb').read(), Float)

    #If data is MxN you'll need to reshape
    x.shape = M,N

Hope this help,
