+
+//! Class for storing data required for delayed unary operations,
+//! such as the operand (e.g. the matrix to which the operation is to be applied) and the unary operator (e.g. inverse).
+//! The operand is stored as a reference (which can be optimised away),
+//! while the operator is "stored" through the template definition (op_type).
+//! The operands can be 'Mat', 'Row', 'Col', 'Op', and 'Glue'.
+//! Note that as 'Glue' can be one of the operands, more than one matrix can be stored.
+//!
+//! For example, we could have:
+//! Op< Glue< Mat, Mat, glue_times >, op_htrans >
+
+template<typename T1, typename op_type>
+class Op : public Base<typename T1::elem_type, Op<T1, op_type> >
+  {
+  public:
+  
+  typedef typename T1::elem_type                   elem_type;
+  typedef typename get_pod_type<elem_type>::result pod_type;
+  
+  inline explicit Op(const T1& in_m);
+  inline          Op(const T1& in_m, const elem_type in_aux);
+  inline          Op(const T1& in_m, const elem_type in_aux,         const uword in_aux_uword_a, const uword in_aux_uword_b);
+  inline          Op(const T1& in_m, const uword     in_aux_uword_a, const uword in_aux_uword_b);
+  inline          Op(const T1& in_m, const uword     in_aux_uword_a, const uword in_aux_uword_b, const uword in_aux_uword_c, const char junk);
