I have only implemented the decompositions for real matrices. At the
moment the best way to operate on complex matrices is with LAPACK,
passing the elements of the gsl_matrix object as arguments.  I'm
hoping someone might add the complex matrix decompositions to GSL one
day.

Hi,
 
I want to use GSL in an optimization problem. The 
calculations involved require various matrix and vector operations using 
complex numbers. Does GSL support complex matrix operations such as: 
Inverses, cholesky decomposition and other more basic operations ? I would 
be very grateful if somebody can advice me as to the complex matrix capabilities 
of GSL.
