Undefined function or variable 'ispc'.
Warning: MATLAB did not appear to successfully set the search path. To recover for this session of
MATLAB, type "restoredefaultpath;matlabrc". To find out how to avoid this warning the next time you
start MATLAB, type "docsearch problem path" after recovering for this session.
Warning: Duplicate directory name: D:\Program Files\MATLAB\R2010b\toolbox\local.

解決方法是:
1. 在matlab的command里輸入: restoredefaultpath;matlabrc. 回車等待執行完畢.
2. cd到'你的安裝目錄'\MATLAB\R2011b\toolbox\local.
3. 執行命令 "savepath pathdef.m".
改問題得到解決, 再次啟動MATLAB不會再出現該Warning.
