Scalar1VectorBinary()

template<typename E1 , typename E2 , typename F >

CDPL::Math::Scalar1VectorBinary< E1, E2, F >::Scalar1VectorBinary ( const Expression1Type &  e1, const Expression2Type &  e2  )

inline

Constructs the expression-template node combining the scalar e1 and the vector expression e2.

Member Function Documentation

getSize()

template<typename E1 , typename E2 , typename F >

SizeType CDPL::Math::Scalar1VectorBinary< E1, E2, F >::getSize ( ) const

inline

Returns the wrapped vector expression's size.

Returns

The element count.

operator()()

template<typename E1 , typename E2 , typename F >

ConstReference CDPL::Math::Scalar1VectorBinary< E1, E2, F >::operator() ( SizeType  i ) const

inline

Applies the binary functor to the scalar and element i of the wrapped vector expression and returns the result.

Parameters

i	The zero-based element index.
