- *
- *	Dawson's Integral
- *
- *
- *
- * SYNOPSIS:
- *
- * double x, y, dawsn();
- *
- * y = dawsn( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Approximates the integral
- *
- *                             x
- *                             -
- *                      2     | |        2
- *  dawsn(x)  =  exp( -x  )   |    exp( t  ) dt
- *                          | |
- *                           -
- *                           0
- *
- * Three different rational approximations are employed, for
- * the intervals 0 to 3.25; 3.25 to 6.25; and 6.25 up.
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE      0,10        10000       6.9e-16     1.0e-16
- *    DEC       0,10         6000       7.4e-17     1.4e-17
