-------------------------------
Summary: Add apply method to Vector/Matrix
Key: HAMA-765
URL: https://issues.apache.org/jira/browse/HAMA-765
Project: Hama
Issue Type: Improvement
Environment: 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.
