public class BroadcastScalarArray
extends BaseShapedArray

Specialized array class representing the broadcasting of a scalar value to fill an entire array. Generally not mutable.

Method Summary

Modifier and Type	Method and Description
static INDArray	create(double value, int[] targetShape)
BroadcastScalarArray	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
boolean	isFullyMutable() If this method returns true, the INDArray is guaranteed to be fully mutable in all positions i.e.
boolean	isView() Return true if this array is considered as a view type.
void	set(int[] indexes, double value) Sets the element at the given indexed position in a mutable array
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

Method Detail

create

public static INDArray create(double value,
                              int[] targetShape)

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

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.

isFullyMutable

public boolean isFullyMutable()

Description copied from interface: INDArray

If this method returns true, the INDArray is guaranteed to be fully mutable in all positions i.e. every position can store any valid double value

Specified by:

isFullyMutable in interface INDArray

Overrides:

isFullyMutable in class AbstractArray<INDArray>

get

public double get()

Description copied from interface: INDArray

Returns the double value of a scalar array

Specified by:

get in interface INDArray

Specified by:

get in class AbstractArray<INDArray>

get

public double get(int x)

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 class AbstractArray<INDArray>

get

public double get(int x,
                  int y)

Description copied from interface: INDArray

Returns the double value at the specified position in a 2D matrix

Specified by:

get in interface INDArray

Specified by:

get in class AbstractArray<INDArray>

exactClone

public BroadcastScalarArray 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
