Vectorpublic void foreachActive(scala.Function2<Object,Object,scala.runtime.BoxedUnit> f)
Vectorf to all the active elements of dense and sparse vector.
foreachActive in interface Vectorf - the function takes two parameters where the first parameter is the index of
the vector with type Int, and the second parameter is the corresponding value
with type Double.public boolean equals(Object other)
