-/** @file
- * @brief Defines the various combinations of vector expressions.
- *
- * Create unary and binary operators with macros. The available combinations
- * are:
- *
- * Unary expressions:
- *
- * op Vector -> Vector
- * op VecXpr -> VecXpr
- *
- * Binary expressions:
- *
- * Vector op Vector -> Vector
- * VecXpr op Vector -> VecXpr
- * Vector op VecXpr -> VecXpr
- * VecXpr op VecXpr -> VecXpr
- *
- * Vector op Scalar -> Vector
- * Scalar op Vector -> Vector
- * VecXpr op Scalar -> VecXpr
- * Scalar op VecXpr -> VecXpr
- *
- * All of the generator functions compress the expression tree by hoisting
- * subexpressions into the containing expression. This has the effect of
- * forcing only the root node of the expression tree to be a VectorXpr.
- * Every other node is a Unary or BinaryVectorOp.
- *
- * @todo Should ScalarT in expressions be passed by reference or by value?
