template<typename NumericT >
void viennacl::linalg::opencl::detail::scan_impl ( vector_base< NumericT > const &  input,

bool  is_inclusive 
)

Worker routine for scan routines using OpenCL.

Note on performance: For non-in-place scans one could optimize away the temporary 'opencl_carries'-array. This, however, only provides small savings in the latency-dominated regime, yet would effectively double the amount of code to maintain.

Returns the OpenCL kernel string for the operation C = A * B with A sparse, B, C dense matrices.
