  • Method Details

    • upper

      public static boolean upper(DSubmatrixD1 T)
    • lower

      public static boolean lower(DSubmatrixD1 T)
    • upper

      public static boolean upper(double[] T, int indexT, int n)
      Performs an inline upper Cholesky decomposition on an inner row-major matrix. Only the upper triangular portion of the matrix is read or written to.
      Parameters:
      T - Array containing an inner row-major matrix. Modified.
      indexT - First index of the inner row-major matrix.
      n - Number of rows and columns of the matrix.
      Returns:
      If the decomposition succeeded.
    • lower

      public static boolean lower(double[] T, int indexT, int n)
      Performs an inline lower Cholesky decomposition on an inner row-major matrix. Only the lower triangular portion of the matrix is read or written to.
      Parameters:
      T - Array containing an inner row-major matrix. Modified.
      indexT - First index of the inner row-major matrix.
      n - Number of rows and columns of the matrix.
      Returns:
      If the decomposition succeeded.
