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_0x dt \exp(-t2). |
erf_Q |
This routine computes the upper tail of the Gaussian probability function Q(x) = (1/\sqrt{2\pi}) \int_x\infty dt \exp(-t2/2). |
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(-t2/2). |
