Method Detail

extractWhereTrue

public Tensor<V> extractWhereTrue(Tensor<java.lang.Boolean> mask)

Extracts from the tensor only those elements where the values in the given mask is true. The resulting tensors will then have the same dimensionality as the original tensor, but will only have that many elements as there are true elements in the mask tensor.

Parameters:

mask - the mask which determines which elements shall be present in the new tensor.

Returns:

A tensor which will contain only those elements which have true flags in the mask

extractCoordinatesOfType

public <C1> java.util.Set<C1> extractCoordinatesOfType(java.lang.Class<C1> coordinateType)

Retrieves all the unique coordinates of the given type.

Parameters:

coordinateType - the type of the coordinate to extract

Returns:

a set of extracted coordinates
