MATLAB启动时报错: pathdef.m not found 问题解决方法
在win7 64位上安装Matlab R2011b后, 启动出现一串warning.
Warning: D:\Program Files\MATLAB\R2010b\toolbox\local\pathdef.m not found. Toolbox Path Cache is not being used. Type 'help toolbox_path_cache' for more info 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. Warning: Initializing Handle Graphics failed in matlabrc. This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was: MATLAB:UndefinedFunction Undefined function or method 'colordef' for input arguments of type 'double'. > In matlabrc at 100 Warning: Initializing Java preferences failed in matlabrc. This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was: MATLAB:UndefinedFunction Undefined function or method 'usejava' for input arguments of type 'char'. > In matlabrc at 123 Warning: Failed to add default profiler filters. > In matlabrc at 179
解决方法是:
1. 在matlab的command里输入: restoredefaultpath;matlabrc. 回车等待执行完毕.
2. cd到'你的安装目录'\MATLAB\R2011b\toolbox\local.
3. 执行命令 "savepath pathdef.m".
改问题得到解决, 再次启动MATLAB不会再出现该Warning.
