Detailed Description
template<typename T, typename S = typename mln::value::props< T >::sum, typename M = S>
struct mln::accu::stat::deviation< T, S, M >
Generic standard deviation accumulator class.
Parameter T is the type of values that we sum. Parameter S is the type to store the standard deviation; the default type of S is the summation type (property) of T. Parameter M is the type of the mean value; the default type of M is S.
