%  Every function has a help text. Input parameters are described with name,
%  data type and a description. For example:
%   method (StringT) : Method
%     = 'cbf': ...
%     = 'capon': ...
%  where "method" is the parameter name, "StringT" is the data type and the
%  rest the description.
%  Data type names are shown in parentheses and they start with a capital
%  letter and end with a capital T. Data type definitions can be found in [1]
%  or by "help dbtdata".
%  [D] = This parameter can be omitted and then a default value is used.
%  When the [D]-input parameter is not the last used in the call, it must be
%  given the value [], i.e. an empty matrix.
%  ... = There can be more parameters. They are explained under respective
%  metod or choice.
%
%  For more information about the functions use "help" for the corresponding
%  function.
