Package cern.jet.math

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.
