DoubleDenseNdArray

protected DoubleDenseNdArray(DoubleDataBuffer buffer,
                             Shape shape)

Method Detail

create

public static DoubleNdArray create(DoubleDataBuffer buffer,
                                   Shape shape)

getDouble

public double getDouble(long... indices)

Description copied from interface: DoubleNdArray

Returns the double value of the scalar found at the given coordinates.

To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:

  DoubleNdArray matrix = NdArrays.ofDoubles(shape(2, 2));  // matrix rank = 2
  matrix.getDouble(0, 1);  // succeeds, returns 0.0
  matrix.getDouble(0);  // throws IllegalRankException

  DoubleNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
  scalar.getDouble();  // succeeds, returns 0.0
 

Specified by:

getDouble in interface DoubleNdArray

Parameters:

indices - coordinates of the scalar to resolve

Returns:

value of that scalar

setDouble

public DoubleNdArray setDouble(double value,
                               long... indices)

Description copied from interface: DoubleNdArray

Assigns the double value of the scalar found at the given coordinates.

To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:

  DoubleNdArray matrix = NdArrays.ofDoubles(shape(2, 2));  // matrix rank = 2
  matrix.setDouble(10.0, 0, 1);  // succeeds
  matrix.setDouble(10.0, 0);  // throws IllegalRankException

  DoubleNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
  scalar.setDouble(10.0);  // succeeds
 

Specified by:

setDouble in interface DoubleNdArray

Parameters:

value - value to assign

indices - coordinates of the scalar to assign

Returns:

this array

copyTo

public DoubleNdArray copyTo(NdArray<Double> dst)

Description copied from interface: NdArray

Copy the content of this array to the destination array.

The NdArray.shape() of the destination array must be equal to the shape of this array, or an exception is thrown. After the copy, the content of both arrays can be altered independently, without affecting each other.

Specified by:

copyTo in interface DoubleNdArray

Specified by:

copyTo in interface NdArray<Double>

Parameters:

dst - array to receive a copy of the content of this array

Returns:

this array

read

public DoubleNdArray read(DoubleDataBuffer dst)

Specified by:

read in interface DoubleNdArray

write

public DoubleNdArray write(DoubleDataBuffer src)

Specified by:

write in interface DoubleNdArray

buffer

protected DoubleDataBuffer buffer()

Specified by:

buffer in class AbstractDenseNdArray<Double,DoubleNdArray>
