Re: matrix inversion

There wasn't but I've added a new complex LU decomposition to the CVS
repository, gsl_linalg_complex_LU_decomp(), since it is the same as
the the real case.  We need someone to write the other complex matrix
decompositions though -- they are more difficult.

There are some additional functions for solving a linear system
gsl_linalg_complex_LU_solve() and calculating the inverse
gsl_linalg_complex_LU_invert()in the same file (linalg/luc.c).

As mentioned there might be a safer alternative to the direct
calculation of the inverse, depending what you want to do with it.
