Subject git commit: Added getInterpolatedSecondaryDerivatives to ContinuousOutputModel.
Date Wed, 22 Oct 2014 19:40:45 GMT
Repository: commons-math
Updated Branches:
  refs/heads/master f8e6bc8ec -> 45ae5c7e4


Added getInterpolatedSecondaryDerivatives to ContinuousOutputModel.

This method is a close relative to getInterpolatedDerivatives, but is
associated with the secondary state.

JIRA: MATH-1160
