Method Detail

length

int length()

Returns the length of a vector, in terms of the number of elements. For Euclidean length, use magnitude() instead

Returns:

get

double get(int i)

Gets a specified element from a vector.

Specified by:

get in interface INDArray

set

void set(int i,
         double value)

Set a specified element in a vector

Specified by:

set in interface INDArray

addCopy

AVector addCopy(AVector a)

Adds a vector element-wise to this vector, returning a new vector.

Parameters:

a -

Returns:

subCopy

AVector subCopy(AVector a)

Subtracts a vector element-wise from this vector, returning a new vector.

Parameters:

a -

Returns:

multiplyCopy

AVector multiplyCopy(AVector a)

Multiplies a vector element-wise with this vector, returning a new vector.

Parameters:

a -

Returns:

divideCopy

AVector divideCopy(AVector a)

Divides this vector element-wise by another vector, returning a new vector.

Parameters:

a -

Returns:

sqrtCopy

AVector sqrtCopy()

Computes the square root for each element in this vector, returning a new vector.

Parameters:

a -

Returns:

epsilonEquals

boolean epsilonEquals(AVector v,
                      double tolerance)

normalise

double normalise()

normaliseCopy

AVector normaliseCopy()

Normalises this vector to unit length, returning a new vector.

Returns:

clone

AVector clone()

Description copied from interface: INDArray

Returns a clone of the array data, as a new array which will be fully mutable and may be of a different class to the original. Clone should attempt to return the most efficient possible array type. Clone should preserve sparsity property where possible, but this is not guaranteed.

Specified by:

clone in interface INDArray

isSameShape

boolean isSameShape(AVector a)

Returns true if this vector is exactly the same shape as another vector.

Parameters:

a -

Returns:

shiftCopy

AVector shiftCopy(int shift)

Shifts a vector by the specified number of elements, filling with zeros. Returns a new vector.

Parameters:

shift -

Returns:

rotateView

AVector rotateView(int shift)

Rotates a vector by the specified number of elements, wrapping around element values. Returns a view.

Parameters:

shift -

Returns:

rotateCopy

AVector rotateCopy(int shift)

Rotates a vector by the specified number of elements, wrapping around element values. Returns a new vector.

Parameters:

shift -

Returns:
