Dear Mohammed, I believe the GSL does not have implementations of the real hyperbolic trigonometric functions. It only has for the gsl_complex numbers (see link [1]). If you want to get the sinh, cosh, and tanh of double, float, or long double precision you can use the <math.h> system library (see link [2]).
I hope it helps :-) [1]: http://www.gnu.org/s/gsl/manual/html_node/Complex-Hyperbolic-Functions.html [2]: http://www.cplusplus.com/reference/clibrary/cmath/ *Alejandro Cámara *Department of Optics - UCM http://www.acamara.es/ 2011/10/14 mohammed shqeeer <shqe...@hotmail.com> > > dear sir > i am trying to define sinh ,cosh, tanh , coth , in gsl library but i cant > can you help me > note i am mhmd shqeeer > i am phd student > > _______________________________________________ > Help-gsl mailing list > Help-gsl@gnu.org > https://lists.gnu.org/mailman/listinfo/help-gsl > _______________________________________________ Help-gsl mailing list Help-gsl@gnu.org https://lists.gnu.org/mailman/listinfo/help-gsl
