Class expression_moving_sum¶

`class` expression_moving_sum<U, E1, STag, stateless> dsp ¶

template <typename U, typename E1, univector_tag STag, bool stateless = false>
struct expression_moving_sum : expression_with_traits<E1> { … }

Template expression performing a moving sum (rectangular window) over the input.

Maintains a running sum updated incrementally as samples enter and leave the window. The state may be owned or referenced.

Template parameters
U	Sample/value type.
E1	Input expression type.
STag	`univector_tag` of the delay line storage.
stateless	If `true` , the state is held by reference.
