Class LongMult

java.lang.Object

cern.jet.math.tlong.LongMult

All Implemented Interfaces:

LongFunction

public final class LongMult
extends Object
implements LongFunction

Only for performance tuning of compute longensive 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. Longended to be passed to matrix.assign(function) methods.
