Class for storing data required for delayed binary operations, 00023 //! such as the operands (e.g. two matrices) and the binary operator (e.g. addition). 00024 //! The operands are stored as references (which can be optimised away), 00025 //! while the operator is "stored" through the template definition (glue_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 two matrices can be stored. 00028 //! 00029 //! For example, we could have: Glue<Mat, Mat, glue_times> 00030 //! 00031 //! Another example is: Glue< Op<Mat, op_trans>, Op<Mat, op_inv>, glue_times > 00032 00033 00034 00035 template<typename T1, typename T2, typename glue_type> 00036 class Glue : public Base<typename T1::elem_type, Glue<T1, T2, glue_type> > 00037 { 00038 public: 00039 00040 typedef typename T1::elem_type elem_type; 00041 typedef typename get_pod_type<elem_type>::result pod_type; 00042 00043 arma_inline Glue(const T1& in_A, const T2& in_B); 00044 arma_inline Glue(const T1& in_A, const T2& in_B, const u32 in_aux_u32); 00045 arma_inline ~Glue(); 00046 00047 const T1& A; //!< first operand 00048 const T2& B; //!< second operand 00049 const u32 aux_u32; //!< storage of auxiliary data, u32 format 00050 }; 00051 00052 00053 00054 //! @}
