[Numpy-discussion] saving complex vector

[Neal Becker]

Simple question.  I want to save a complex vector as text in format

real_0 imag_0\n
real_1 imag_1\n
...

I thought to use something like:
np.savetxt ('gen_qpsk.txt', (mod_out.real, mod_out.imag), fmt='%g %g\n')

I need a way to reinterpret the complex data as an array with 2 columns to 
make this work.  Ideas?
