function v = f_version (s)

%F_VERSION: Return version number of requested item
%
% Usage: v = f_version (s)
%
% Inputs: 
%          s = an optional string specifying the item whose 
%              version is being requested.  Default = 'MATLAB'
%
%              'MATLAB' = MATLAB verison number
%              'FDSP'   = FDSP version number
% Outputs:
%          v = a double containing version number of requested item

in nargin < 1
   s = 'MATLAB';
