Subject [jira] Created: (MATH-281) RealMatrix.subtract javadoc typo
Date Sat, 01 Aug 2009 17:46:14 GMT
RealMatrix.subtract javadoc typo
--------------------------------

                 Key: MATH-281
                 URL: https://issues.apache.org/jira/browse/MATH-281
             Project: Commons Math
          Issue Type: Bug
            Reporter: Albert Huang
            Priority: Minor


I think the javadoc for RealMatrix.subtract is wrong.  It says "@return this + m", which perhaps
should be "@return this - m"

Index: src/main/java/org/apache/commons/math/linear/RealMatrix.java
