Subject [jira] [Commented] (MATH-809) Expressions and functions interpreter
Date Fri, 06 Jul 2012 14:05:35 GMT


Guillaume Chauvet commented on MATH-809:

Thank you for your explanations, Gilles. I think it's possible to provide an alternative implementation
without frontend by implementing the interpreter design pattern (to keeping goal of commons-math).
I will send a mail to dev list to discuss about this potential new feature.
