Detailed Description

template<class _incrementalOperationType, class _elementOperationType>
class SoViSi< _incrementalOperationType, _elementOperationType >

Implement operation of the form \(s_o = op_{incr}(op(v_i, s_i))\) for fixed size vectors.

This class uses template specialization to perform incremental binary vector operations of the form

\[s_o = \mathrm{op_{incr}(\mathrm{op}(v_i, s_i))} \]

where \(v_i\) and \(s_i\) are the input vector and scalar and \(s_o\) is the scalar output. The vector has a fixed size, determined at compilation time, op stands for the unary operation performed elementwise on \(v_i\) and \(s_i\) and whose result are used incrementally as input for \(op_{incr}\). For a vector of size 3, the result is \(s_o = op_{incr}(op_{incr}(op(v[1], s), op(v[0], s)), op(v, s))\).

Parameters

_incrementalOperationType	The type of the incremental operation.
_elementOperationType	The type of the unary operation.

OutputType SoViSi< _incrementalOperationType, _elementOperationType >::Unfold ( const _inputVectorType & inputVector, const _inputScalarType & inputScalar )

inlinestatic

Unfold the recursion. Performs the operation _elementOperationType elementwise on the last elements of the input vector and the input scalar and call Unfold for the _size - 1 elements left (i.e. unfold the recursive calls). The incremental operation is applied to the result of the recursive Unfold call and the result of _elementOperationType(inputVector[_size], inputScalar[_size]).

Parameters

inputVector	The input vector (first operand for _elementOperationType).
inputScalar	The input scalar (second operand for _elementOperationType).
