One reason I never did a complex version was that I wanted to also have complex versions for the general polygamma functions (not just the first), and I was too tired to do all of that. But since there is some demand, I have now implemented psi(z) for complex z. It is checked into CVS, but it is not tested yet. The problem is that I cannot get test_sf.c to build; it fails to find some symbols from the library for complex math, declared in gsl/complex/gsl_complex_math.h. Brian, can you look at this and figure out what is going on? If I can get the tests to build, I can wrap this up. -- Gerard Jungman Los Alamos National Laboratory
