Chris@49 14 //! Class for storing data required for delayed binary operations,
Chris@49 15 //! such as the operands (e.g. two matrices) and the binary operator (e.g. addition).
Chris@49 16 //! The operands are stored as references (which can be optimised away),
Chris@49 17 //! while the operator is "stored" through the template definition (glue_type).
Chris@49 18 //! The operands can be 'Mat', 'Row', 'Col', 'Op', and 'Glue'.
Chris@49 19 //! Note that as 'Glue' can be one of the operands, more than two matrices can be stored.
Chris@49 20 //!
Chris@49 21 //! For example, we could have: Glue<Mat, Mat, glue_times>
Chris@49 22 //!
Chris@49 23 //! Another example is: Glue< Op<Mat, op_htrans>, Op<Mat, op_inv>, glue_times >
