Gilles commented on MATH-1420:
------------------------------
You should post on the "dev" ML of the "Commons" project.
There, please provide more details on the intended audience of this
functionality (use-cases).
But be aware that "Commons Math" is being refactored into more manageable
codebases (new components and/or modules); and human resources are scarce for
such a big task (help welcome, see the list of JIRA issues...).
Personally, I'd be wary to add parsing code to "Commons Math" since it is
mainly a repository of numerical algorithms; the contents of your project might
be better suited to another component.
>From the above example, I'd suggest "Commons Text"...

> Key: MATH-1420
> URL: https://issues.apache.org/jira/browse/MATH-1420
> Project: Commons Math
> Issue Type: New Feature
> Affects Versions: 3.6.1
> Reporter: Ernie DeFoy
> Labels: newbie
>
> I have a system that parses mathematical expressions and can symbolically
> differentiate, reduce and evaluate mathematical expressions. It is able to
> be expanded to integrate, and I think it is written well for the most part.
> For example:
> >> System.out.println(calculus.diff("4*x^2 - csc(x^3)"));
> 8*x+3*x^2*cot(x^3)*csc(x^3)
> or
> 8x + 3x^2cot(x^3)csc(x^3)
> I wonder if this would be useful/relevant to the Apache project. I would
> love to create a pull request and add this feature
