Module rgsl::error

The error function is described in Abramowitz & Stegun, Chapter 7.

Functions

erf	This routine computes the error function erf(x), where erf(x) = (2/\sqrt(\pi)) \int_0^x dt \exp(-t^2).
erf_Q	This routine computes the upper tail of the Gaussian probability function Q(x) = (1/\sqrt{2\pi}) \int_x^\infty dt \exp(-t^2/2).
erf_Q_e	This routine computes the upper tail of the Gaussian probability function Q(x) = (1/\sqrt{2\pi}) \int_x^\infty dt \exp(-t^2/2).
erf_Z	This routine computes the Gaussian probability density function Z(x) = (1/\sqrt{2\pi}) \exp(-x^2/2).
erf_Z_e	This routine computes the Gaussian probability density function Z(x) = (1/\sqrt{2\pi}) \exp(-x^2/2).
erf_e	This routine computes the error function erf(x), where erf(x) = (2/\sqrt(\pi)) \int_0^x dt \exp(-t^2).
erfc	This routine computes the complementary error function erfc(x) = 1 - erf(x) = (2/\sqrt(\pi)) \int_x^\infty \exp(-t^2).
erfc_e	This routine computes the complementary error function erfc(x) = 1 - erf(x) = (2/\sqrt(\pi)) \int_x^\infty \exp(-t^2).
hazard	This routine computes the hazard function for the normal distribution.
hazard_e	This routine computes the hazard function for the normal distribution.
log_erfc	This routine computes the logarithm of the complementary error function \log(\erfc(x)).
log_erfc_e	This routine computes the logarithm of the complementary error function \log(\erfc(x)).
set_error_handler	f is the type of GSL error handler functions. An error handler will be passed four arguments which specify the reason for the error (a string), the name of the source file in which it occurred (also a string), the line number in that file (an integer) and the error number (an integer). The source file and line number are set at compile time using the FILE and LINE directives in the preprocessor. An error handler function returns type void. Error handler functions should be defined like this,
set_error_handler_off	This function turns off the error handler by defining an error handler which does nothing. This will cause the program to continue after any error, so the return values from any library routines must be checked. This is the recommended behavior for production programs. The previous handler is returned (so that you can restore it later).
