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].

  2. class DenseVector extends Vector

    A dense vector represented by a value array.

    A dense vector represented by a value array.

    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].

  7. 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
