Iterated integrals of the complementary error function

[Erik Leunissen]

L.S.

As part of a computation, I need to evaluate iterated integrals of the 
complementary error function (also called "repeated integrals of ...").

I didn't find them implemented as a function, neither by pure octave, 
neither by the specfun package.

Is there any facility that I might have overlooked?


Thanks in advance for your attention,
