stddev( Expr [, T nan] [, double mean] )
[Double valued reductions]

Functions

• template<class Expr , int N> double ltl::stddev (const ExprBase< Expr, N > &e, double *avg=NULL)
• template<class Expr , int N> double ltl::stddev (const ExprBase< Expr, N > &e, typename Expr::value_type nan, double *avg=NULL)

---

Detailed Description

Return standard deviation of Expr optionally neglecting values == nan and optionally store mean to pointed address. // = sqrt( variance(...) )
