T	meow::noEPS (T value, T eps=1e-9)
	如果abs(輸入的數值) < eps, 則回傳0, 否則回傳輸入的數值 More...
template<class T >
T	meow::normalize (T lower, T upper, T value)
	(value-lower)/(upper-lower) More...
template<class T >
T	meow::denormalize (T lower, T upper, T _ratio)
	(lower+_ratio*(upper-lower)) More...
template<class T >
T	meow::ratioMapping (T l1, T u1, T m1, T l2, T u2)
	denormalize(l2,u2,normalize(l1,u1,m1)) More...

template<class T >
double	meow::average (T const &beg, T const &end, T const &p, double sigs)
	只將 sigs 個標準差以內的數據拿來取平均, 不過這次用 p 來加權平均 More...
