Package org.apache.sysds.runtime.data

Class TensorIndexes

java.lang.Object

org.apache.sysds.runtime.data.TensorIndexes

All Implemented Interfaces:

Externalizable, Serializable, Comparable<TensorIndexes>, org.apache.hadoop.io.Writable, org.apache.hadoop.io.WritableComparable<TensorIndexes>

public class TensorIndexes
extends Object
implements org.apache.hadoop.io.WritableComparable<TensorIndexes>, Externalizable

This represent the indexes to the blocks of the tensor. Please note that these indexes are 1-based, whereas the data in the block are zero-based (as they are double arrays).
