Method Detail

getIndices

public Indices getIndices()

Description copied from class: Tensor

Returns indices of this tensor.

Specified by:

getIndices in class Tensor

Returns:

indices of this tensor

remove

public abstract Tensor remove(int position)

Removes tensor at the specified position and returns the result.

Parameters:

position - position in tensor

Returns:

result of removing

remove

public Tensor remove(Tensor tensor)

Removes the first occurrence of the specified tensor (reference) from this list, if it is present. If the tensor does not contain the element, it is unchanged. More formally, removes the element with the lowest index i such that t == get(i) (if such an element exists).

Parameters:

tensor - specified reference

Returns:

result of removing

remove

public Tensor remove(int[] positions)

Removes tensors at the specified positions and returns the result.

Parameters:

positions - position in tensor

Returns:

result of removing

Throws:

java.lang.IndexOutOfBoundsException

select

public Tensor select(int[] positions)

Selects tensors at the specified positions and puts it together.

Parameters:

positions - positions in tensor

Returns:

result subtensor
