max@0: //! Class for storing data required for delayed unary operations,
max@0: //! such as the operand (e.g. the matrix to which the operation is to be applied) and the unary operator (e.g. inverse).
max@0: //! The operand is stored as a reference (which can be optimised away),
max@0: //! while the operator is "stored" through the template definition (op_type).
max@0: //! The operands can be 'Mat', 'Row', 'Col', 'Op', and 'Glue'.
max@0: //! Note that as 'Glue' can be one of the operands, more than one matrix can be stored.
max@0: //!
max@0: //! For example, we could have:
max@0: //! Op< Glue< Mat, Mat, glue_times >, op_htrans >
