Thanks Gilles, I'm currently trying to dive into all of this a bit and just wondering: Will there still be new releases of commons-math3, or is it postponed in favor of math4? I'm asking this because it might be an option to add erf(x) support to Derivative structure in math3 first (as it

[math] DerivativeStructure and erf/erfx

2020-08-13 Thread Christoph Läubrich
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
