Use implementation of JAMA for ArrayRealVector operators
--------------------------------------------------------
Key: MATH-623
URL: https://issues.apache.org/jira/browse/MATH-623
Project: Commons Math
Issue Type: Improvement
Affects Versions: 3.0
Reporter: Arne Plöse
Priority: Minor
For instance the add(double[] v) fist clones the array, and then adds all
entries of this.data to the result.
JAMA uses the following approach create a empty result[] the assign the sum of
each entry to the result. this is approximately 10 -20 % faster.
I will provide a patch with some more enhancements/cleanups for this.
in the test look for XXX:
the first number is the jama time the second the current algorithm.
