Class FloatMult

java.lang.Object

cern.jet.math.tfloat.FloatMult

All Implemented Interfaces:

FloatFunction

public final class FloatMult
extends java.lang.Object
implements FloatFunction

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.
