- Constructor Detail
  - ArrayRealVector
```
public ArrayRealVector()
```
    Build a 0-length vector. Zero-length vectors may be used to initialized construction of vectors by data gathering. We start with zero-length and use either the ArrayRealVector(ArrayRealVector, ArrayRealVector) constructor or one of the append method (append(double), append(ArrayRealVector)) to gather data into this vector.
  - ArrayRealVector
```
public ArrayRealVector(int size)
```
    Construct a vector of zeroes.
    
    Parameters:
    size - Size of the vector.
  - ArrayRealVector
```
public ArrayRealVector(int size,
               double preset)
```
    Construct a vector with preset values.
    
    Parameters:

```
public ArrayRealVector(double[] d,
               boolean copyArray)
```
    Create a new ArrayRealVector using the input array as the underlying data array. If an array is built specially in order to be embedded in a ArrayRealVector and not used directly, the copyArray may be set to false. This will prevent the copying and improve performance as no new array will be built and no data will be copied.
    
    Parameters:
    d - Data for the new vector.
    copyArray - if true, the input array will be copied, otherwise it will be referenced.

    Specified by:
    
    isNaN in class RealVector
    
    Returns:
    true if any coordinate of this vector is NaN, false otherwise.
  - isInfinite
```
public boolean isInfinite()
```
    Check whether any coordinate of this vector is infinite and none are NaN.
    
    Specified by:
    
    isInfinite in class RealVector
    
    Returns:
    true if any coordinate of this vector is infinite and none are NaN, false otherwise.
  - equals
```
public boolean equals(Object other)
```
    Test for the equality of two real vectors. If all coordinates of two real vectors are exactly the same, and none are NaN, the two real vectors are considered to be equal. NaN coordinates are considered to affect globally the vector and be equals to each other - i.e, if either (or all) coordinates of the real vector are equal to NaN, the real vector is equal to a vector with all NaN coordinates.
    
    This method must be overriden by concrete subclasses of RealVector (the current implementation throws an exception).
    
    Overrides:
    
    equals in class RealVector
    
    Parameters:
    other - Object to test for equality.
    
    Returns:
    true if two vector objects are equal, false if other is null, not an instance of RealVector, or not equal to this RealVector instance.
  - hashCode
```
public int hashCode()
```
    . This method must be overriden by concrete subclasses of RealVector (current implementation throws an exception). All NaN values have the same hash code.
    
    Overrides:
    
    hashCode in class RealVector

                      double b,
                      RealVector y)
```

    combineToSelf in class RealVector
    
    Parameters:
    a - Weight of this.
    b - Weight of y.
    y - Vector with which this is linearly combined.

```
public double walkInOptimizedOrder(RealVectorPreservingVisitor visitor)
