NAME
PDL::GSLSF::AIRY - PDL interface to GSL Special Functions DESCRIPTION
This is an interface to the Special Function package present in the GNU Scientific Library. SYNOPSIS
FUNCTIONS
gsl_sf_airy_Ai Signature: (double x(); double [o]y(); double [o]e()) Airy Function Ai(x). gsl_sf_airy_Ai 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_airy_Bi Signature: (double x(); double [o]y(); double [o]e()) Airy Function Bi(x). gsl_sf_airy_Bi 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_airy_Ai_scaled Signature: (double x(); double [o]y(); double [o]e()) Scaled Airy Function Ai(x). Ai(x) for x < 0 and exp(+2/3 x^{3/2}) Ai(x) for x > 0. gsl_sf_airy_Ai_scaled 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_airy_Bi_scaled Signature: (double x(); double [o]y(); double [o]e()) Scaled Airy Function Bi(x). Bi(x) for x < 0 and exp(+2/3 x^{3/2}) Bi(x) for x > 0. gsl_sf_airy_Bi_scaled 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_airy_Ai_deriv Signature: (double x(); double [o]y(); double [o]e()) Derivative Airy Function Ai`(x). gsl_sf_airy_Ai_deriv 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_airy_Bi_deriv Signature: (double x(); double [o]y(); double [o]e()) Derivative Airy Function Bi`(x). gsl_sf_airy_Bi_deriv 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_airy_Ai_deriv_scaled Signature: (double x(); double [o]y(); double [o]e()) Derivative Scaled Airy Function Ai(x). Ai`(x) for x < 0 and exp(+2/3 x^{3/2}) Ai`(x) for x > 0. gsl_sf_airy_Ai_deriv_scaled 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_airy_Bi_deriv_scaled Signature: (double x(); double [o]y(); double [o]e()) Derivative Scaled Airy Function Bi(x). Bi`(x) for x < 0 and exp(+2/3 x^{3/2}) Bi`(x) for x > 0. gsl_sf_airy_Bi_deriv_scaled does not process bad values.
