Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_keyval2cfg”.

  FT_KEYVAL2CFG converts between a structure and a cell-array with key-value
  pairs which can be used for optional input arguments. 
  
  Use as
    [cfg] = ft_keyval2cfg(varargin)
