Subject [jira] [Commented] (MATH-683) Create a method shift in the PolynomialFunction class
Date Thu, 06 Oct 2011 15:49:30 GMT

    [ https://issues.apache.org/jira/browse/MATH-683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13122018#comment-13122018
] 

Gilles commented on MATH-683:
-----------------------------

I also changed the return type of the method, in order to emphasize the transformation of
the coefficients. It is trivial for the user to create the "PolynomialFunction".

value.
> The polynomial sum(ai * k^i) turns into sum(ai * (k+a)^i)
