7.9 Dawson Function

The Dawson integral is defined by \exp(-x^2) \int_0^x dt \exp(t^2). A table of Dawson’s integral can be found in Abramowitz & Stegun, Table 7.5. The Dawson functions are declared in the header file gsl_sf_dawson.h.

Function: double gsl_sf_dawson (double x)
Function: int gsl_sf_dawson_e (double x, gsl_sf_result * result)

These routines compute the value of Dawson’s integral for x.
