- Constructor Detail
  - ArrayFieldVector
```
public ArrayFieldVector(Field<T> fieldIn)
```
    Build a 0-length vector. Zero-length vectors may be used to initialize construction of vectors by data gathering. We start with zero-length and use either the ArrayFieldVector(ArrayFieldVector, ArrayFieldVector) constructor or one of the append methods (add(FieldVector) or append(ArrayFieldVector)) to gather data into this vector.
    
    Parameters:
    
    fieldIn - field to which the elements belong
  - ArrayFieldVector
```
public ArrayFieldVector(Field<T> fieldIn,
                        int size)
```
    Construct a vector of zeroes.
    
    Parameters:
    
    fieldIn - Field to which the elements belong.
    
    size - Size of the vector.
  - ArrayFieldVector
```
public ArrayFieldVector(int size,
                        T preset)
```
    Construct a vector with preset values.
    
    Parameters:
    
    size - Size of the vector.
    
    preset - All entries will be set with this value.
  - ArrayFieldVector
```
public ArrayFieldVector(T[] d)
```
    Construct a vector from an array, copying the input array. This constructor needs a non-empty d array to retrieve the field from its first element. This implies it cannot build 0 length vectors. To build vectors from any size, one should use the ArrayFieldVector(Field, FieldElement[]) constructor.
    
    Parameters:
    
    d - Array.
    
    Throws:
    
    NullArgumentException - if d is null.
    
    ZeroException - if d is empty.
    
    See Also:

  - ArrayFieldVector
```
public ArrayFieldVector(Field<T> fieldIn,
                        T[] d)
```
    Construct a vector from an array, copying the input array.
    
    Parameters:
    
    fieldIn - Field to which the elements belong.
    
    d - Array.
    
    Throws:
    
    NullArgumentException - if d is null.

  - ArrayFieldVector
```
public ArrayFieldVector(T[] d,
                        boolean copyArray)
```
    Create a new ArrayFieldVector using the input array as the underlying data array. If an array is built specially in order to be embedded in a ArrayFieldVector 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. This constructor needs a non-empty d array to retrieve the field from its first element. This implies it cannot build 0 length vectors. To build vectors from any size, one should use the ArrayFieldVector(Field, FieldElement[], boolean) constructor.
    
    Parameters:
    
    d - Data for the new vector.
    
    copyArray - If true, the input array will be copied, otherwise it will be referenced.
    
    Throws:
    
    NullArgumentException - if d is null.
    
    ZeroException - if d is empty.

```
    Create a new ArrayFieldVector using the input array as the underlying data array. If an array is built specially in order to be embedded in a ArrayFieldVector and not used directly, the copyArray may be set to false.
