| std::pair<double, double> calculate_statistics | -( | -const std::vector< long > | -values | ) | -- |
-
-
-Calculate the mean and variance from the result of the run_benchmark.
-- Parameters
-
-
-
-[in] values Vector with result values.
-
- Returns
- std::pair where the first element is mean and the second one is standard deviation.
- Note
- It's not a general mean/stddev function it only works properly when feed with data from the benchmark function.
