function out = pulse2sdt(varargin);

%PULSE2SDT interface between SDT and Bruel&Kjaer Pulse software
%
%  Note that you can also use PULSE universal file export capabilities
%  and read the data using UFREAD.
%
%  Accepted commands are 
%
%  pulse2sdt(Group1) : converts datasets read with the BridgeTo Matlab
%       to SDT format. By default the dataset is displayed with iiplot,
%       if you wish something else use an output argument.
%
%  pulse2sdt('read') : lets you select a PulseAscii file and displays the 
%       result using iiplot. This requires the Bridge to Matlab 
%       http://www.bksv.com/bksv/?MIval=bk_view_Document&ID=973
