Mult

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

All Implemented Interfaces:

DoubleFunction
```
public final class Mult
extends java.lang.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.
