The Matlab erf function does not support complex arguments:

That's an alternative. Yet i
Can the contributed functions be given names that don't conflict with
the current Octave ones, like erf_complex? That way there should be no
problem with putting them either in specfun or as their own Octave
package.

Also keep in mind that this will need to be compatible with
the Matlab complex erf(z).

Hi Steven,
Some comments below with regards to Jordi's observations on integration.

There is an updated version of my package
(http://ab-initio.mit.edu/Faddeeva) which computes not only the Faddeeva
function (the scaled complex error function) but also the ordinary erf
and erfc functions of complex arguments, as well as the erfcx and erfi
variants and the Dawson function (a sc

The complex error function (generalizing erf, erfc, and erfx) is used in
lots of fields. We needed it to solve electromagnetic scattering

Hi all, in case there is interest I wanted to let you know that I've
written a free complex-argument error function in C++ with an Octave
wrapper at:

(This is the Faddeeva function w(z), which is equivalent to erfcx(iz)
where erfcx is
