Class for storing data required for delayed unary operations on a sparse +//! matrix that produce a dense matrix; the data for storage may include +//! the operand (eg. the matrix to which the operation is to be applied) and the unary operator (eg. 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 'SpMat', 'SpRow', 'SpCol', 'SpOp', and 'SpGlue'. +//! Note that as 'SpGlue' can be one of the operands, more than one matrix can be stored. +//! +//!
