To recover for this session ofMATLAB, type "restoredefaultpath;matlabrc". To find out how to avoid this warning the next time youstart MATLAB, type "docsearch problem path" after recovering for this session.

解决方法是:

1. 在matlab的command里输入: restoredefaultpath;matlabrc. 回车等待执行完毕.

2. 在Matlab的命令行中，使用cd命令，将工作路径切换至'你的安装目录'\MATLAB\R2011b\toolbox\local.

3. 执行命令 "savepath pathdef.m".

该问题得到解决, 再次启动MATLAB不会再出现该Warning.
