Class for storing data required for delayed unary operations, 00023 //! such as the operand (e.g. the matrix to which the operation is to be applied) and the unary operator (e.g. inverse). 00024 //! The operand is stored as a reference (which can be optimised away), 00025 //! while the operator is "stored" through the template definition (op_type). 00026 //! The operands can be 'Mat', 'Row', 'Col', 'Op', and 'Glue'. 00027 //! Note that as 'Glue' can be one of the operands, more than one matrix can be stored. 00028 //! 00029 //! For example, we could have: 00030 //!
