Subject svn commit: r680172 - in /commons/proper/math/branches/MATH_2_0/src/site/xdoc/userguide: index.xml linear.xml
Date Sun, 27 Jul 2008 19:48:17 GMT
Author: luc

New Revision: 680172

URL: http://svn.apache.org/viewvc?rev=680172&view=rev
Log:
Support for one dimensional vectors has been added to the linear algebra
package with a RealVector interface, a RealVectorImpl default implementation
using a single double array to store elements and a RealVectorFormat class for
input/output.
