Method Detail

create

public static AVector create(AMatrix source,
                             int band)

addToArray

public void addToArray(double[] data,
                       int offset)

Description copied from class: AVector

Adds this vector to a double[] array, starting at the specified offset.

Specified by:

addToArray in interface INDArray

Overrides:

addToArray in class AVector

getElements

public void getElements(double[] data,
                        int offset)

Description copied from interface: INDArray

Copies all elements of this array a double array at the specified offset

Specified by:

getElements in interface INDArray

Overrides:

getElements in class AMatrixViewVector

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 AMatrixViewVector

unsafeSet

public void unsafeSet(int i,
                      double v)

Description copied from class: AVector

Overrides:

unsafeSet in class AMatrixViewVector

exactClone

public AVector 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:

A clone of the original array

dotProduct

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

Description copied from class: AVector

Specified by:

dotProduct in class AVector

applyOp

public void applyOp(Op op)

Description copied from interface: INDArray

Applies a unary operator to all elements of the array (in-place)

Specified by:

applyOp in interface INDArray

Overrides:

applyOp in class AVector
