[jira] [Created] (MATH-574) Remove the restriction that the two
vectors in RealVector.outerProduct have to be of the same size.
Remove the restriction that the two vectors in RealVector.outerProduct have to be of the same size.
---------------------------------------------------------------------------------------------------
Key: MATH-574
URL: https://issues.apache.org/jira/browse/MATH-574
Project: Commons Math
Issue Type: Improvement
Affects Versions: 2.2, 3.0
Environment: All.
Reporter: Emile Ben Nasatyr
Priority: Minor
Fix For: 3.0
Currently RealMatrix M = x.outerProduct(y) throws an exception if x and y are different sizes. This is as documented in the Javadoc but not what one expects mathematically (see e.g. http://en.wikipedia.org/wiki/Outer_product) - the vectors can be any size.
So please remove the restriction that the vectors should be the same size, as this doesn't seem to be necessary either mathematically or in terms of the implementation.
