Subject [jira] Created: (MATH-341) Test for firsst Derivative in PolynomialFunction ERROR
Date Fri, 05 Feb 2010 20:34:27 GMT
Test for firsst Derivative in PolynomialFunction ERROR
------------------------------------------------------

                 Key: MATH-341
                 URL: https://issues.apache.org/jira/browse/MATH-341
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Roger BAll
         Attachments: FirstDerivativePolyNomTest.java

I have written the attached test using our data for generating a curve function

However the first derivative test fails see: testfirstDerivativeComparisonFullPower

Either my test is in error or there is a bug in PolynomialFunction class.
