scsb_icon_gen.m

CheckMate is a MATLAB-based tool for modeling, simulating and investigating properties of hybrid dyn

% Script file for generating CheckMate switched continuous system block
% (SCSB) mask icon
%
% Syntax:
%   "scsb_icon_gen"
%
% Description:
%   "scsb_icon_gen" generates a figure displaying the SCSB mask icon, and
%   returns the two sets of coordinates used to generate the plot.
%
% Note:
%   "scsb_icon_gen" was used to obtain the sets of coordinates used in
%   "scsb_icon()" which is used to generate the actual mask icon in
%   CheckMate.
