| fea681da | 23 | .SH DESCRIPTION |
| 7d3b7c75 | 24 | The (unimplemented) function |
| c13182ef | 25 | .BR cerf () |
| b5cc2ffb | 26 | is the complex version of the error function. |
| 2bc2f479 | 27 | erf(z) = 2/sqrt(pi) * integral from 0 to z of exp(\-t*t) dt. |
| b5cc2ffb | 28 | The function |
| c13182ef | 29 | .BR cerfc () |
| b5cc2ffb | 30 | is defined as cerfc(z) = 1\-cerf(z). |
| fea681da | 31 | .\" must check 1/sqrt(2*pi) ? |
