Module admm 

Shared ADMM iteration infrastructure for TV-based inversion methods.

Provides pre-allocated buffers and a generic iteration step used by TV-ADMM, NLTV, and RTS algorithms.

Structs

AdmmBuffers

Pre-allocated buffers for ADMM-based inversion algorithms.

Functions

admm_step

Run one ADMM iteration step.

prepare_admm_spectral

Pre-compute ADMM spectral operators (dipole kernel, inverse operator, and RHS).

prepare_fansi_spectral

Pre-compute spectral operators shared by the FANSI-family nonlinear solvers (NDI, nlTV, nlTGV, L1-QSM, WH-QSM, HD-QSM).
