Class SimpleBounds

java.lang.Object

org.apache.commons.math3.optim.SimpleBounds

All Implemented Interfaces:

OptimizationData

public class SimpleBounds
extends java.lang.Object
implements OptimizationData

Simple optimization constraints: lower and upper bounds. The valid range of the parameters is an interval that can be infinite (in one or both directions).
Immutable class.

Since:

SimpleBounds

public SimpleBounds(double[] lB,
            double[] uB)

Parameters:

lB - Lower bounds.

uB - Upper bounds.

Method Detail

getLower

public double[] getLower()

Gets the lower bounds.

Returns:

the lower bounds.

getUpper

public double[] getUpper()

Gets the upper bounds.

Returns:

the upper bounds.
