public final double[] data

Method Detail

getArray

public final double[] getArray()

Gets the underlying data array for this array-backed matrix. Mutation of this data array is possible, but caution is advised as this may cause unpredictable side effects if the array is aliased elsewhere

Returns:

get

public double get(int i,
                  int j)

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 interface IMatrix

unsafeGet

public double unsafeGet(int i,
                        int j)

Description copied from class: AMatrix
