> Key: MATH-1005
> URL: https://issues.apache.org/jira/browse/MATH-1005
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.2
> Reporter: Roman Werpachowski
> Fix For: 3.3

>
> When MathArrays.linearCombination is passed arguments with length 1, it
> throws an ArrayOutOfBoundsException. This is caused by this line:
> double prodHighNext = prodHigh[1];
> linearCombination should check the length of the arguments and fall back to
> simple multiplication if length == 1.
