    • 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
