[jira] [Commented] (MATH-682) Pascal triangle

    [ https://issues.apache.org/jira/browse/MATH-682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13119235#comment-13119235 ] 

Sébastien Brisard commented on MATH-682:
----------------------------------------

I have an implementation based on JScience which I need to port to Commons-Math for personal use. I use it for symbolic calcs on polynomials. I need it to return FieldElement<T>, but it could be easily adapted to double[] as requested.
So, if this indeed is found useful for 3.0 by others, and no one else has any ready piece of code for it, I'm happy to work on that.

> Create a method to get Pascal's triangle coefficient. This method could be implemented in MathUtils, in a static way, with the following signature :
> double[] getTriangleCoefficient(final int order)
