PDL::GSLSF::TRIG - PDL interface to GSL Special Functions
This is an interface to the Special Function package present in the GNU Scientific Library.
Signature: (double x(); double [o]y(); double [o]e())
Sin(x) with GSL semantics.
gsl_sf_sin does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
Signature: (double x(); double [o]y(); double [o]e())
Cos(x) with GSL semantics.
gsl_sf_cos does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
Signature: (double x(); double xx(); double [o]y(); double [o]e())
Hypot(x,xx) with GSL semantics.
gsl_sf_hypot does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
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_sin does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
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_cos does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.

gsl_sf_polar_to_rect does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
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_rect_to_polar does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
Signature: (double [o]y())
Force an angle to lie in the range (-pi,pi].
gsl_sf_angle_restrict_symm does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
Signature: (double [o]y())
Force an angle to lie in the range [0,2 pi).
gsl_sf_angle_restrict_pos does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
Signature: (double x(); double dx(); double [o]y(); double [o]e())
Sin(x) for quantity with an associated error.
gsl_sf_sin_err does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input piddles.
