Method Detail

fromCOO

public SparseVector fromCOO(int size,
                            scala.collection.Seq<scala.Tuple2<Object,Object>> entries)

Constructs a sparse vector from a coordinate list (COO) representation where each entry is stored as a tuple of (index, value).

Parameters:

size -

entries -

Returns:

fromCOO

public SparseVector fromCOO(int size,
                            scala.collection.Iterable<scala.Tuple2<Object,Object>> entries)

Constructs a sparse vector from a coordinate list (COO) representation where each entry is stored as a tuple of (index, value).

Parameters:

size -

entries -

Returns:

fromCOO

public SparseVector fromCOO(int size,
                            scala.Tuple2<Object,Object> entry)

Convenience method to be able to instantiate a SparseVector with a single element. The Scala type inference mechanism cannot infer that the second tuple value has to be of type Double if only a single tuple is provided.

Parameters:

size -

entry -

Returns:

sparseVectorConverter

public Object sparseVectorConverter()

BreezeVectorConverter implementation for SparseVector

This allows to convert Breeze vectors into SparseVector
