struct FWDLIB::fitUserRec

Workspace for the linear least-squares fit of Berg-Scherg parameters in the EEG sphere model (SVD matrices, residuals, weights).

Example​

No example of its own: Workspace of the Berg-Scherg least-squares fit inside FwdEegSphereModel::fwd_eeg_fit_berg_scherg; built and consumed only there.

It is exercised by:

src/examples/ex_fwd_api/main.cpp
std::unique_ptr<FwdEegSphereModelSet> models(FwdEegSphereModelSet::fwd_add_default_eeg_sphere_model(nullptr));
std::unique_ptr<FwdEegSphereModel> sphere(models->fwd_select_eeg_sphere_model("Default")); // 4 layers: brain, CSF, skull, scalp
// Scalp radius 90 mm; 3 Berg-Scherg dipoles approximate the layered potentials
sphere->fwd_setup_eeg_sphere_model(0.09f, true, 3);
sphere->r0 = Vector3f(0.0f, 0.0f, 0.04f);
auto els = FwdCoilSet::create_eeg_els(eeg, eeg.size());
VectorXf V(els->ncoil());
FwdEegSphereModel::fwd_eeg_spherepot_coil(rd, Q, *els, V, sphere.get()); // V per A m
