[Help-gsl] vector views

Just wondering if someone can help me out with using vector views.  I have a 
set of N complex numbers which I am storing in a 2*N size gsl_vector.  I am 
using this because I am looking for the solution of a nonlinear system, and, to 
the best of my knowledge, the multidimensional root finding algorithms only 
take functions with gsl_vector arguments.

So here's my question, does anyone have any tips on how to set up vector views 
so that I have pointers available that logically map to the real and imaginary 
portions of the vector?  I.e.,  I want

gsl_vector * z // Size 2*N
gsl_vector * a // Size N, a= Re z
gsl_vector * b// Size N, b= Im z
