FwdCoil

Namespace: FWDLIB  ·  Library: Forward Library

#include <fwd/fwd_coil.h>

class FWDLIB::FwdCoil

Implements FwdCoil (replaces fwdCoil / fwdCoilRec from MNE-C fwd_types.h).

Single MEG sensor coil or EEG electrode — stores the coil-local frame and the ``(r_mag, cos_mag, w) integration-point triples that approximate the Biot-Savart surface integral over the coil area.

Public Methods​

FwdCoil(p_np)​

Constructs the Forward Coil.

FwdCoil(p_FwdCoil)​

Copy constructor.

Parameters:

  • p_FwdCoil : const FwdCoil & FwdCoil which should be copied.

~FwdCoil()​

Destroys the Forward Coil description.

is_axial_coil()​

Checks if this is an axial coil.

Returns:

  • bool — True if axial coil, false otherwise.

is_magnetometer_coil()​

Checks if this is an magnetometer.

Returns:

  • bool — True if magnetometer, false otherwise.

is_planar_coil()​

Checks if this is an planar coil.

Returns:

  • bool — True if planar coil, false otherwise.

is_eeg_electrode()​

Checks if this is an EEG electrode.

Returns:

  • bool — True if EEG electrode, false otherwise.

pos(j)​

Return a read-only map to the j-th integration point position (3 contiguous floats).

dir(j)​

Return a read-only map to the j-th integration point direction cosine.

Static Methods​

create_eeg_el(ch, t)​

Create an electrode definition.

Transform coordinate frame if so desired.

Parameters:

Returns:

  • FwdCoil::UPtr — The created coil.
