Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help beamformer_sam”.

  BEAMFORMER_SAM scans on pre-defined dipole locations with a single
  dipole and returns the CTF Synthetic Aperture Magnetometry (SAM)
  beamformer estimates. location. Dipole locations that are outside
  the head will return a NaN value.
 
  Use as
    [dipout] = beamformer_sam(dipin, sens, headmodel, dat, cov, varargin)
  where
    dipin       is the input dipole model
    sens        is the gradiometer definition
    headmodel   is the volume conductor definition
    dat         is the data matrix with the ERP or ERF
    cov         is the data covariance or cross-spectral density matrix
  and
    dipout      is the resulting dipole model with all details
 
  The input dipole model consists of
    dipin.pos   positions for dipole, e.g. regular grid
    dipin.mom   dipole orientation (optional)
 
  Additional options should be specified in key-value pairs and can be
    ...
 
  These options influence the forward computation of the leadfield
    'reducerank'      = reduce the leadfield rank, can be 'no' or a number (e.g. 2)
    'normalize'       = normalize the leadfield
    'normalizeparam'  = parameter for depth normalization (default = 0.5)
