compex vector in 'C' -> complex vector in 'octave'

[James Sherman Jr.]

I'm not sure how "elegant" it is, but I'd just do

y = x(1:2:end) + x(2:2:end)*i;

The best solution is probably just put this in your own
"read_complex_vector" function and just use that whenever you want to
read in that file format.

Hope this helps.
