If you just want to add your matrix to an existing ascii file, you can
open this file in append mode and give the file handle to
numpy.savetxt :
f_handle = file('my_file.dat', 'a')
savetxt(f_handle, my_matrix)
f_handle.close()

Hi,
At http://scipy.org/Generate_Documentation you can find a very small
documentation generator for NumPy/SciPy modules based on pyparsing
package (by Paul McGuire). I am not sure if this belongs to where I put
it, so feel free to (re)move the page as needed. I hope it might be
interesting

I'm trying to convert a character array to a floating point array. I'm
using one of the recent svn builds. It is surprising that astype does
not do the job. However if I first convert the char array to an array
and then use astype everything works fine. Is this a bug?

Sameer,
I can't tell whether it's a bug or a feature, but I can give you some
explanation: when you call .astype on your chararray, you call the
__array_finalize__ of the chararray, which requires the dtype to be string
like. Obviously, that won't work in your case. Transforming the chararray
a does not seem to be an array, so it is not surprising that you need to
convert it to an array first.

Well, a *IS* a regular chararray, and therefore a subclass of ndarray (try
isinstance). The problem isn't here, it's that the

Thanks for the reply. Well, I built my Python stuff, including NumPy
previously, before I changed to the higher GCC version. Do you know if
there's an option I can toggle that will specify Apple's GCC to be
used?
