Type Members

  1. type RowMap = SortedLinkedHashMap[Int, Double]

    Shorthand type definition for sparse vector

Value Members

  1. def ++(b: Double, u: SparseVectorD): SparseVectorD

    Concatenate scalar 'b' and vector 'u'.

    Concatenate scalar 'b' and vector 'u'.

    b

    the scalar to be concatenated - first part

    u

    the vector to be concatenated - second part

  2. def apply(xs: Array[String], skip: Int): SparseVectorD

    Create a SparseVectorD from an array of Strings, skipping the first 'skip' elements.

    Create a SparseVectorD from an array of Strings, skipping the first 'skip' elements. If an element is non-numeric, use its hashcode. FIX: Might be better to map non-numeric Strings to ordinal values.

    xs

    the array of the Strings

    skip

    the number of elements at the beginning to skip (e.g., id column)

  3. def apply(xs: Array[String]): SparseVectorD

    Create a SparseVectorD from an array of Strings.

    Create a SparseVectorD from an array of Strings.

    xs

    the array of the Strings

  4. def apply(x: String, xs: String*): SparseVectorD

    Create a SparseVectorD from one or more values (repeated values String*).

    Create a SparseVectorD from one or more values (repeated values String*).

    x

    the first String

    xs

    the rest of the Strings

  5. def apply(xs: Seq[Double]): SparseVectorD

    Create a SparseVectorD from a sequence of Doubles.

    Create a SparseVectorD from a sequence of Doubles.

    xs

    the sequence of the Double numbers

  6. def apply(x: Double, xs: Double*): SparseVectorD

    Create a SparseVectorD from one or more values (repeated values Double*).

    Create a SparseVectorD from one or more values (repeated values Double*).

    x

    the first Double number

    xs

    the rest of the Double numbers

  7. def range(start: Int, end: Int): SparseVectorD

    Return a SparseVectorD containing a sequence of increasing integers in a range.

    Return a SparseVectorD containing a sequence of increasing integers in a range.

    start

    the start value of the vector, inclusive

    end

    the end value of the vector, exclusive (i.e., the first value not returned)
