Subject svn commit: r1383441 - in /commons/proper/math/trunk/src: main/java/org/apache/commons/math3/analysis/ main/java/org/apache/commons/math3/analysis/differentiation/ main/java/org/apache/commons/math3/analysis/function/ main/java/org/apache/commons/math3...
Date Tue, 11 Sep 2012 14:56:41 GMT
Author: luc
Date: Tue Sep 11 14:56:39 2012
New Revision: 1383441

URL: http://svn.apache.org/viewvc?rev=1383441&view=rev
Log:
Renamed UnivariateDifferentiable into UnivariateDifferentiableFunction.

The "Function" part of the name was forgotten when this new interface
was created a few weeks ago, for replacing the older
DifferentiableUnivariateFunction.

Added:
    commons/proper/math/trunk/src/main/java/org/apache/commons/math3/analysis/differentiation/UnivariateDifferentiableFunction.java   (contents, props changed)
      - copied, changed from r1383437, commons/proper/math/trunk/src/main/java/org/apache/commons/math3/analysis/differentiation/UnivariateDifferentiable.java
