PDL::GSLSF::TRIG - PDL interface to GSL Special Functions DESCRIPTION
This is an interface to the Special Function package present in the GNU Scientific Library. SYNOPSIS
Functions FUNCTIONS
gsl_sf_sin Signature: (double x(); double [o]y(); double [o]e()) Sin(x) with GSL semantics. gsl_sf_cos Signature: (double x(); double [o]y(); double [o]e()) Cos(x) with GSL semantics. gsl_sf_hypot Signature: (double x(); double xx(); double [o]y(); double [o]e()) Hypot(x,xx) with GSL semantics. gsl_sf_complex_sin Signature: (double zr(); double zi(); double [o]x(); double [o]y(); double [o]xe(); double [o]ye()) Sin(z) for complex z gsl_sf_complex_cos Signature: (double zr(); double zi(); double [o]x(); double [o]y(); double [o]xe(); double [o]ye()) Cos(z) for complex z gsl_sf_complex_logsin Signature: (double zr(); double zi(); double [o]x(); double [o]y(); double [o]xe(); double [o]ye()) Log(Sin(z)) for complex z gsl_sf_lnsinh Signature: (double x(); double [o]y(); double [o]e()) Log(Sinh(x)) with GSL semantics. gsl_sf_lncosh Signature: (double x(); double [o]y(); double [o]e()) Log(Cos(x)) with GSL semantics. gsl_sf_polar_to_rect Signature: (double r(); double t(); double [o]x(); double [o]y(); double [o]xe(); double [o]ye()) Convert polar to rectlinear coordinates. gsl_sf_rect_to_polar Signature: (double x(); double y(); double [o]r(); double [o]t(); double [o]re(); double [o]te()) Convert rectlinear to polar coordinates. return argument in range [-pi, pi]. gsl_sf_angle_restrict_symm Signature: (double [o]y()) Force an angle to lie in the range (-pi,pi]. gsl_sf_angle_restrict_pos Signature: (double [o]y()) Force an angle to lie in the range [0,2 pi). gsl_sf_sin_err Signature: (double x(); double dx(); double [o]y(); double [o]e()) Sin(x) for quantity with an associated error. gsl_sf_cos_err Signature: (double x(); double dx(); double [o]y(); double [o]e()) Cos(x) for quantity with an associated error.
