Yexi Jiang updated HAMA-765:
----------------------------
Description:
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.
