Method Summary

Modifier and Type	Method and Description
void	applyOp(Op op) Applies a unary operator to all elements of the array (in-place)
int	componentCount() Returns the number of components of this array.
INDArray	exactClone() Creates a deep clone of an array, using the same class implementation as the original array
double	get() Returns the double value of a scalar array
double	get(int... indexes) Returns the double value at the specified index position in an array
double	get(int x) Returns the double value at the specified position in a 1D vector
double	get(int x, int y) Returns the double value at the specified position in a 2D matrix
INDArray	getComponent(int k) Gets a component from the array at the specified index Will throw an error if components are not supported, or if the component is out of bounds as defined by 0 <= k
boolean	isView() Return true if this array is considered as a view type.
static INDArray	join(INDArray a, INDArray b, int dim)
void	set(int[] indexes, double value) Sets the element at the given indexed position in a mutable array
void	setSparse(double v) Sets the non-sparse elements of this array to the specified value May throw an exception if non-sparse elements are not mutable
INDArray	slice(int majorSlice) Returns the specified major slice of this array as a view (slice along dimension 0) 0 dimensional slice results are permitted, but attempting to slice a 0 dimensional array will result in an error.
INDArray	slice(int dimension, int index) Returns a slice view of this array along the specified dimension
void	validate() Validates the internal data structure of the INDArray.

Method Detail

join

public static INDArray join(INDArray a,
                            INDArray b,
                            int dim)

get

public double get(int... indexes)

Description copied from interface: INDArray

Returns the double value at the specified index position in an array

set

public void set(int[] indexes,
                double value)

Description copied from interface: INDArray

Sets the element at the given indexed position in a mutable array

slice

public INDArray slice(int majorSlice)

Description copied from interface: INDArray

Returns the specified major slice of this array as a view (slice along dimension 0) 0 dimensional slice results are permitted, but attempting to slice a 0 dimensional array will result in an error.

slice

public INDArray slice(int dimension,
                      int index)

Description copied from interface: INDArray

Returns a slice view of this array along the specified dimension

componentCount

public int componentCount()

Description copied from interface: INDArray

Returns the number of components of this array. May return 0 if components are not supported

Specified by:

componentCount in interface INDArray

Overrides:

componentCount in class AbstractArray<INDArray>

Returns:

getComponent

public INDArray getComponent(int k)

Description copied from interface: INDArray

Gets a component from the array at the specified index Will throw an error if components are not supported, or if the component is out of bounds as defined by 0 <= k

Specified by:

getComponent in interface INDArray

Overrides:

getComponent in class AbstractArray<INDArray>

Returns:

isView

public boolean isView()

Description copied from interface: INDArray

Return true if this array is considered as a view type. This indicates (but does not guarantee): a) Data is *likely* to be shared with other arrays, so mutation of one may affect others b) It is *unlikely* to be in the most efficient general purpose format isView is intended to be used as for heuristics. It should *not* be used where the outcome might affect correctness.

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 AbstractArray<INDArray>

exactClone

public INDArray exactClone()

Description copied from interface: INDArray

Creates a deep clone of an array, using the same class implementation as the original array

Returns:

A clone of the original array

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

Overrides:

validate in class AbstractArray<INDArray>

get

public double get()

Description copied from interface: INDArray

Specified by:

get in class AbstractArray<INDArray>

setSparse

public void setSparse(double v)

Description copied from interface: INDArray
