 +  <a href=/​reference/​beamformer_sam><​font color=green>​BEAMFORMER_SAM</​font></​a>​ 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)
