Brian, Thanks for the reply. I will certainly apply what you are suggesting

I think your warning can be avoided without a cast by using the prototype double g1(double, void *) which matches the definition in GSL. Otherwise, the appropriate cast would be (double (*)(double, void *)). See the header file gsl_math.h for the definition of the gsl_function type. -- best regards, Brian Gough (GSL Maintainer) Network Theory Ltd, Publishing the GSL Manual - http://www.network-theory.co.uk/gsl/manual/ --------------------------------- The best gets better.
