Detailed Description

Legacy MNE-C noise covariance container preserved for cross-toolchain compatibility.

Author: Christoph Dinh chris.nosp@m.toph.nosp@m..dinh.nosp@m.@mne.nosp@m.-cpp..nosp@m.org

Since: 2.0.0

Date: March 2026

MNELIB::MNECovMatrix mirrors the mneCovMatrixRec struct of the original MNE C tooling: a dense or diagonal noise covariance kept as a vector plus eigen-decomposition, used internally by routines ported verbatim from mne_inverse_operator. New code should prefer FIFFLIB::FiffCov; this class exists so legacy algorithms can be translated without rewriting their algebra.
