Constructor Detail

NDArrayList

public NDArrayList()

NDArrayList

public NDArrayList(INDArray container)

Specify the underlying ndarray for this list.

Parameters:

container - the underlying array.

Method Detail

array

public INDArray array()

Get a view of the underlying array relative to the size of the actual array. (Sometimes there are overflows in the internals but you want to use the internal INDArray for computing something directly, this gives you the relevant subset that reflects the content of the list)

Overrides:

array in class BaseNDArrayList<Double>

Returns:

the view of the underlying ndarray relative to the collection's real size

size
