## Detailed Description

### template<typename ElementOutput_, int Count, typename ElementAccumulator_ = ElementOutput_, typename ElementCompute_ = ElementOutput_, FloatRoundStyle Round = FloatRoundStyle::round_to_nearest>
class cutlass::epilogue::thread::LinearCombination< ElementOutput_, Count, ElementAccumulator_, ElementCompute_, Round >

Applies a linear combination operator to an array of elements.

D = alpha * accumulator + beta * source + uniform
