在新版本的Matlab使用过程中很多之前做的模型都无法打开，归根到底是因为在模型中使用了中文编码，解决这个问题可以从以下几个方面入手：

%在Matlab中输入以下指令就可以打开以前版本的Simulink程序了。
%%%%%%%%%%%%%%%%%%%%%%方案1%%%%%%%%%%%%%%%%%%%%%%%%%%%%

bdclose all
set_param(0,'CharacterEncoding','ISO-8859-1')

%%%%%%%%%%%%%%%%%%%%%%方案2%%%%%%%%%%%%%%%%%%%%%%%%%%%%

bdclose all
set_param(0,'CharacterEncoding','windows-1252')

%%%%%%%%%%%%%%%%%%%%%%恢复编码%%%%%%%%%%%%%%%%%%%%%%%%%
%恢复编码可采用重启Matlab或者命令窗口输入以下指令

bdclose all
set_param(0,'CharacterEncoding','ibm-1386_P100-2002')
