//! \addtogroup Op
//! @{



//! 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 >
