Chris@49 14 //! Class for storing data required for delayed unary operations,
Chris@49 15 //! such as the operand (e.g. the matrix to which the operation is to be applied) and the unary operator (e.g. inverse).
Chris@49 16 //! The operand is stored as a reference (which can be optimised away),
Chris@49 17 //! while the operator is "stored" through the template definition (op_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 one matrix can be stored.
Chris@49 20 //!
Chris@49 21 //! For example, we could have:
Chris@49 22 //! Op< Glue< Mat, Mat, glue_times >, op_htrans >
