Class Mult

java.lang.Object
  cern.jet.math.Mult

All Implemented Interfaces:: DoubleFunction

public final class Mult
extends Object
implements DoubleFunction

Only for performance tuning of compute intensive linear algebraic computations. Constructs functions that return one of

a * constant
a / constant

a is variable, constant is fixed, but for performance reasons publicly accessible. Intended to be passed to matrix.assign(function) methods.

Field Summary
`double`	`multiplicator` Public read/write access to avoid frequent object construction.

Method Summary
`double`	`apply(double a)` Returns the result of the function evaluation.
`static Mult`	`div(double constant)` `a / constant`.
`static Mult`	`mult(double constant)` `a * constant`.
