+% LTPDA_TF is the abstract class which defines transfer functions.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% DESCRIPTION: LTPDA_TF is the abstract class which defines transfer functions.
+%
+% SUPER CLASSES: ltpda_uoh < ltpda_uo < ltpda_obj
+%
+% SUB CLASSES:   miir, mfir, pzmodel, rational, parfrac, ltpda_filter
+%
+% LTPDA_TF PROPERTIES:
+%
+%     Protected Properties (read only)
+%       description   - description of the object
+%       hist          - history of the object (history object)
+%       name          - name of the object
+%       iunits        - input units of the object
+%       ounits        - output  units of the object
+%
+% LTPDA_TF METHODS:
+%
+%     Public Methods
+%       bsubmit         - Bsubmits the given collection of objects to an
+%                         LTPDA Repository.
+%       created         - Returns a time object of the last modification.
+%       creator         - Extract the creator(s) from the history.
+%       eq              - Overloads the == operator for ltpda objects.
+%       get             - Get a property of a object.
+%       index           - Index into a 'ltpda_uoh' object array or matrix.
+%                         This properly captures the history.
+%       isprop          - Tests if the given field is one of the object
+%                         properties.
+%       ne              - Overloads the ~= operator for ltpda objects.
+%       rebuild         - Rebuilds the input objects using the history.
+%       report          - Generates an HTML report about the input objects.
+%       resp            - Returns the complex response of a transfer
+%                         function as an Analysis Object.
+%       save            - Overloads save operator for ltpda objects.
+%       setDescription  - Sets the 'description' property of an ltpda_uoh
+%                         object.
+%       setIunits       - Sets the 'iunits' property of the ao.
+%       setName         - Set the property 'name'.
+%       setOunits       - Sets the 'ounits' property of the ao.
+%       setProperties   - Set different properties of an object.
+%       string          - Writes a command string that can be used to
+%                         recreate the input object(s).
+%       submit          - Submits the given collection of objects to an
+%                         LTPDA Repository.
+%       type            - Converts the input objects to MATLAB functions.
+%
+%     Static Methods
+%       SETS            - Retruns the different sets of the constructor
+%       getDefaultPlist - Returns the default plsit for the specified set-name
+%       getInfo         - Static method to get information of a method
+%       retrieve        - Retrieves a collection of objects from an LTPDA
+%                         repository.
+%
+%     Abstract Methods
+%       char
+%       copy
+%       display
