Hi,
thnaks for the information, I'm currently using the "old" commons-math3
package, would it be possible to use erf with DerivativeStructure there?
> We are looking for volunteer maintainers for the math tools available
for commons math in general or for "commons-numbers"?
I must confess I have only recently noticed that there is development in
commons-math-4 and might be out of date with my knowledge a bit as an
"old" math3 user :-)

I'd like to use the org.apache.commons.math3.special.Erf with a
DerivativeStructure but is seems there is no pre-defined function for
this (like exp()...).
So the question is, can Erf transformed inside a DerivativeStructure
somehow or does the DerivativeStructure need to support that function
directly?
Please note that "Erf" has been moved to the new "Commons Numbers"
component[1], along with the other Gamma-related functions.
The "DerivativeStructure" is one among several utilities that still need to
be ported (and refactored) there.[2]
We are looking for volunteer maintainers for the math tools available from
the Commons libraries. The move to more focused, smaller, components
should hopefully simplify development...
Best,
Gilles
