Constructor & Destructor Documentation

HPIFitData()

HPIFitData::HPIFitData ( )

explicit

Default constructor.

Definition at line 74 of file hpifitdata.cpp.

Member Function Documentation

compare()

bool HPIFitData::compare ( HPISortStruct  a, HPISortStruct  b  )

staticprotected

Compare function for sorting

Definition at line 215 of file hpifitdata.cpp.

compute_leadfield()

Eigen::MatrixXd HPIFitData::compute_leadfield ( const Eigen::MatrixXd &  matPos, const SensorSet &  sensors  )

protected

compute_leadfield computes a forward solution for a dipole in a a volume conductor model. The forward solution is expressed as the leadfield matrix (Nchan*3), where each column corresponds with the potential or field distributions on all sensors for one of the x,y,z-orientations of the dipole. The function has been compared with matlab ft_compute_leadfield and it gives same output.

Definition at line 166 of file hpifitdata.cpp.

dipfitError()

DipFitError HPIFitData::dipfitError ( const Eigen::MatrixXd &  matPos, const Eigen::MatrixXd &  matData, const SensorSet &  sensors, const Eigen::MatrixXd &  matProjectors  )

protected

dipfitError computes the error between measured and model data and can be used for non-linear fitting of dipole position. The function has been compared with matlab dipfit_error and it gives same output

Definition at line 180 of file hpifitdata.cpp.

doDipfitConcurrent()

void HPIFitData::doDipfitConcurrent

(

)

dipfit function is adapted from Fieldtrip Software.

Definition at line 81 of file hpifitdata.cpp.

fminsearch()

Eigen::MatrixXd HPIFitData::fminsearch ( const Eigen::MatrixXd &  matPos, int  iMaxiter, int  iMaxfun, int  iDisplay, const Eigen::MatrixXd &  matData, const Eigen::MatrixXd &  matProjectors, const SensorSet &  sensors, int &  iSimplexNumitr  )

protected

fminsearch Multidimensional unconstrained nonlinear minimization (Nelder-Mead). X = fminsearch(X0, iMaxiter, iMaxfun, iDisplay, matData, sensors) starts at X0 and attempts to find a local minimizer

Definition at line 222 of file hpifitdata.cpp.

magnetic_dipole()

Eigen::MatrixXd HPIFitData::magnetic_dipole ( Eigen::MatrixXd  matPos, Eigen::MatrixXd  matPnt, Eigen::MatrixXd  matOri  )

protected

magnetic_dipole leadfield for a magnetic dipole in an infinite medium. The function has been compared with matlab magnetic_dipole and it gives same output.
