Method Detail

create

public static AVector create(int start,
                             int length)

elementMin

public double elementMin()

Description copied from interface: INDArray

Returns the maximum element value in this array. Throws an error if there are no elements.

Specified by:

elementMin in interface INDArray

Overrides:

elementMin in class AVector

elementMax

public double elementMax()

Description copied from interface: INDArray

Returns the maximum element value in this array. Throws an error if there are no elements.

Specified by:

elementMax in interface INDArray

Overrides:

elementMax in class AVector

elementSum

public double elementSum()

Description copied from class: AVector

Returns the sum of all elements in a vector

Specified by:

elementSum in interface INDArray

Overrides:

elementSum in class AVector

elementSquaredSum

public double elementSquaredSum()

Description copied from interface: INDArray

Returns the sum of squared elements in this array.

Specified by:

elementSquaredSum in interface INDArray

Overrides:

elementSquaredSum in class AVector

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 AComputedVector

unsafeGet

public double unsafeGet(int i)

Description copied from class: AVector

Like get, but performs no bounds checking. Results are undefined if the index is out of range

Overrides:

unsafeGet in class AVector

dotProduct

public double dotProduct(double[] data,
                         int offset)

Description copied from class: AVector

Fast dot product with a double[] array. Performs no bounds checking. Likely to be faster than most other dot product operations

Overrides:

dotProduct in class AComputedVector

subVector

public AVector subVector(int start,
                         int length)

Description copied from class: AVector

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

Overrides:

subVector in class AVector

tryEfficientJoin

public AVector tryEfficientJoin(AVector a)

Description copied from class: AVector

Attempts to perform an efficient join with a second vector. An efficient join is guaranteed to be better than a simple JoinedVector(left,right) If possible, returns the joined vector. If not, returns null

Overrides:

tryEfficientJoin in class AVector
