DECODINGLIB groups the supervised- and unsupervised-decomposition algorithms that turn raw M/EEG into discriminative or regressable features for brain-computer interfaces and pattern-recognition pipelines: Common Spatial Patterns (CSP), Source Power Comodulation (SPoC), Spatio-Spectral Decomposition (SSD), and ICA component labelling. All of these algorithms share the same mathematical skeleton — a generalised eigenvalue problem on two covariance matrices — which is why they live in one compilation unit and not in rtprocessing or dsp.

The header only declares the Qt Q_DECL_EXPORT / Q_DECL_IMPORT macro plus the build-stamp accessors used by the version probe in the applications layer; the actual algorithms are declared in decoding_csp.h, decoding_spoc.h, decoding_ssd.h and decoding_ica_label.h. Keeping the export macro in its own translation unit lets us link DECODINGLIB statically (STATICBUILD) or as a shared library without touching the per-algorithm files.
