Type Members

1. class DenseMatrix extends Matrix

   

   Column-major dense matrix.

   Column-major dense matrix. The entry values are stored in a single array of doubles with columns listed in sequence. For example, the following matrix

   1.0 2.0
   3.0 4.0
   5.0 6.0

   is stored as [1.0, 3.0, 5.0, 2.0, 4.0, 6.0].

   Annotations

   @Since( "2.0.0" )

2. class DenseVector extends Vector

   

   A dense vector represented by a value array.

   A dense vector represented by a value array.

   Annotations

   @Since( "2.0.0" )

3. sealed trait Matrix extends Serializable

   

   Trait for a local matrix.

   Trait for a local matrix.

   Annotations

   @Since( "2.0.0" )

4. class SparseMatrix extends Matrix

   

   Column-major sparse matrix.

   Column-major sparse matrix. The entry values are stored in Compressed Sparse Column (CSC) format. For example, the following matrix

   1.0 0.0 4.0
   0.0 3.0 5.0
   2.0 0.0 6.0

   is stored as values: [1.0, 2.0, 3.0, 4.0, 5.0, 6.0], rowIndices=[0, 2, 1, 0, 1, 2], colPointers=[0, 2, 3, 6].

   Annotations

   @Since( "2.0.0" )

5. class SparseVector extends Vector

   

   A sparse vector represented by an index array and a value array.

   A sparse vector represented by an index array and a value array.

   Annotations

   @Since( "2.0.0" )

6. sealed trait Vector extends Serializable

   

   Represents a numeric vector, whose index type is Int and value type is Double.

   Represents a numeric vector, whose index type is Int and value type is Double.

   Annotations

   @Since( "2.0.0" )
