If you're looking for real-valued hyperbolic functions, your compiler's standard math.h header should have most of what you need: https://secure.wikimedia.org/wikipedia/en/wiki/Math.h. Some things, e.g. coth, you may need to reexpress using other functions. You may find some related elementary functions in GSL listed here: https://www.gnu.org/s/gsl/manual/html_node/Elementary-Functions.html.
If you're looking for complex-valued hyperbolic functions, I think you want this portion of the manual: https://www.gnu.org/s/gsl/manual/html_node/Complex-Hyperbolic-Functions.html Hope that helps, Rhys _______________________________________________ Help-gsl mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-gsl
