Methods

Modifier and Type	Method and Description
IndexedSubVector	exactClone() Returns an exact clone of this vector, i.e.
double	get(int i) Returns the double value at the specified position in a 1D vector
boolean	isView() Returns true if this vector is of a view type that references other vectors / data.
int	length()
void	set(int i, double value)
IndexedSubVector	subVector(int offset, int length) Obtains a sub-vector that refers to this vector.
double	unsafeGet(int i)
void	unsafeSet(int i, double value)
void	validate() Validates the internal data structure of the INDArray.

Method Detail

wrap

public static IndexedSubVector wrap(AVector source,
                    int[] indexes)

get

public double get(int i)

Description copied from interface: INDArray

Returns the double value at the specified position in a 1D vector

Specified by:

get in interface INDArray

Specified by:

get in interface IVector

Specified by:

get in class AVector

Returns:

set

public void set(int i,
       double value)

Specified by:

set in interface INDArray

Specified by:

set in interface IVector

Specified by:

set in class AVector

unsafeGet

public double unsafeGet(int i)

Overrides:

unsafeGet in class AVector

unsafeSet

public void unsafeSet(int i,
             double value)

Overrides:

unsafeSet in class AVector

subVector

public IndexedSubVector subVector(int offset,
                         int length)

Description copied from class: AVector

Obtains a sub-vector that refers to this vector. Changes to the sub-vector will be reflected in this vector

Overrides:

subVector in class AVector

exactClone

public IndexedSubVector exactClone()

Description copied from class: AVector

Returns an exact clone of this vector, i.e. of the same type

Specified by:

exactClone in interface INDArray

Specified by:

exactClone in class AVector

Returns:

validate

public void validate()

Description copied from interface: INDArray

Validates the internal data structure of the INDArray. Throws an exception on failure. Failure indicates a serious bug and/or data corruption.

Specified by:

validate in interface INDArray

isView

public boolean isView()

Description copied from class: AVector

Returns true if this vector is of a view type that references other vectors / data.

Specified by:

isView in interface INDArray

Overrides:

isView in class AVector

Returns:

length

public int length()

Specified by:

length in interface IVector

Specified by:

length in class AVector
