template<typename Func >

output_type MayaFlux::Yantra::MathematicalTransformer< InputType, OutputType >::apply_per_channel ( input_type &  input, Func &&  func  )

inlineprivate

Extracts per-channel spans, applies an in-place func to each, and reconstructs.

Template Parameters

Func	Callable matching void(std::span<double>)

In-place: results are copied back into the original channel spans of input before reconstruction. Out-of-place: input is not mutated.
