Detailed Description

Flux lens state and skew-Burgers flux utilities.

Typedef Documentation

Persistent flux-lens band state and analysis buffers for a simulation context.

The state owns band spectra, physical reconstructions, and bucket arrays after flux_lens_ensure_capacity(); release them with flux_lens_release().

Scratch workspace used while computing and reconstructing flux-lens bands.

The workspace owns temporary buffers and its FFT plan after capacity is ensured; release them with flux_release_scratch() or flux_lens_release().
