◆ compute()

void RooBatchCompute::RF_ARCH::RooBatchComputeClass::compute ( Config const & ,
Computer computer,
std::span< double > output,
VarSpan vars,
ArgSpan extraArgs )
overridevirtual

Compute multiple values using optimized functions.

This method creates a Batches object and passes it to the correct compute function. In case Implicit Multithreading is enabled, the events to be processed are equally divided among the tasks to be generated and computed in parallel.

Parameters
computerAn enum specifying the compute function to be used.
outputThe array where the computation results are stored.
varsA std::span containing pointers to the variables involved in the computation.
extraArgsAn optional std::span containing extra double values that may participate in the computation.
