Hello, 

There are several functions for it, e.g. gsl_vector_complex_real(),...
See the section on "Vector Views" in the manual (copies can be
purchased at http://www.network-theory.co.uk/gsl/manual/)

For matrices, use the matrix row/column views (also in the manual,
same chapter) in combination with these--as James said, the only way
to make a pure real/imag matrix is by copying the elements out, due to
the restrictions on memory layout.
