About F1D&Erf
Hi,

I have a problem when creating a F1D instance with erf(x): F1D f1=new F1D("x+erf(x)");

A pop window showed that the erf(x) can not be parsed.

Dose anyone have any idea?

Thanks for your help!

Hello,

Yes, you can define any function in F1D, but only a limited number are support using string definitions. Here is an example to create 1-Erf function.

It shows that you need to call external Java libraries with special functions
to create "function" object (and such definition can be arbitrary complicated, you can use even if statement as in a program code).

   

best, Sergei
