> Add apply method to Vector/Matrix

> Key: HAMA-765
> URL: https://issues.apache.org/jira/browse/HAMA-765
> Project: Hama
> Issue Type: Improvement
> Affects Versions: 0.6.2
> Reporter: Yexi Jiang
> Assignee: Yexi Jiang
> Priority: Minor
> Fix For: 0.6.3
>
> Attachments: HAMA-765.patch, HAMA-765.patch, HAMA-765.patch,

>
> Add 'apply' method to Vector/Matrix to allow ad-hoc function apply to the
> elements of a Vector/Matrix.
> For example, if a function f( x ) needs to apply to the elements of a vector
> v, then we can use
> ------------
> DoubleFunction fun = new DoubleFunction() {
> public double apply(double element) {
> // do what ever
> }
> };
> v.apply(fun);
> ------------
> This method borrows the style of functional programming by allowing a
> function to apply to all the elements of a Vector/Matrix. It can simply the
> coding, especially for those algorithms where Vector/Matrix operations are
> heavily used.
