%SIGPLOT2WIN_S S-function for plotting radar signals.
%
%--------
%Synopsis:
%  [sys,x0,str,ts] = sigplot2win_s(t,x,u,flag, restParams) 
%
%Description:
%  S-function for plotting radar signals.
%
%   The general form of an M-File S-function syntax is:
%       [SYS,X0,STR,TS] = SFUNC(T,X,U,FLAG,P1,...,Pn)
%
%   Optional parameters, P1,...,Pn can be provided to the S-function and
%   used during any FLAG operation.
