    function result = coder_options(method,varargin)

%% This is a centralized repository of various coder options
%% that drive Stateflow Code Generation.
%% Usage:
%% sfc('coder_options') 
%% without any arguments returns the options strcuture
%% sfc('coder_options','ignoreChecksums') returns the value of this option
%% sfc('coder_options','ignoreChecksums',1) sets the option to 1
%% For more info on the options, look at the comments in this file.
