  • Method Summary

    Modifier and Type
    Method
    Description
    default <N extends Comparable<N>, DN extends MatrixDecomposition<N>>
    DN
    decompose(Access2D.Collectable<N, ? super TransformableRegion<N>> matrix)
    Will create a new decomposition instance and directly perform the decomposition.
    default D
    make()
    Will create a new decomposition instance suitable for typical/most cases.
    default D
    make(int nbRows, int nbCols)
    Will create a new decomposition instance suitable for matrices of the specified size.
    D
    make(Structure2D typical)
    Will create a new decomposition instance suitable for matrices of the specified size.

  • Method Details

    • decompose

      default <N extends Comparable<N>, DN extends MatrixDecomposition<N>> DN decompose(Access2D.Collectable<N, ? super TransformableRegion<N>> matrix)
      Will create a new decomposition instance and directly perform the decomposition.

    • make

      default D make()
      Will create a new decomposition instance suitable for typical/most cases.

      To calculate the decomposition you then need to call the decompose(Access2D.Collectable) method.

      Returns:
      A "decomposer" ready to decompose matrices.

    • make

      default D make(int nbRows, int nbCols)
      Will create a new decomposition instance suitable for matrices of the specified size.

      To calculate the decomposition you then need to call the decompose(Access2D.Collectable) method.

      Parameters:
      nbRows - The expected number of rows in the matrices to decompose
      nbCols - The expected number of columns in the matrices to decompose
      Returns:
      A "decomposer" ready to decompose matrices.

    • make

      D make(Structure2D typical)
      Will create a new decomposition instance suitable for matrices of the specified size.

      To calculate the decomposition you then need to call the decompose(Access2D.Collectable) method.

      Parameters:
      typical - A 2D structure of roughly the expected size with which this decomposition will be used.
      Returns:
      A "decomposer" ready to decompose matrices.
