Class FComplexMult

java.lang.Object

cern.jet.math.tfcomplex.FComplexMult

All Implemented Interfaces:

FComplexFComplexFunction

public final class FComplexMult
extends java.lang.Object
implements FComplexFComplexFunction

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.
