加载轮廓时出错

Question

我最近在更新到 ubuntu 14.04 64bit 时遇到了这个错误。我无法理解发生了什么。怀疑 PATH/LIBRARY 等错误。尝试加载与 MCR 一起使用的程序时也会发生类似情况。可能是什么问题呢？这些错误很常见，但同时也很难找到答案。提前致谢。

当我使用时

Z = 峰值(20); >> 轮廓f(Z,10)

我得到了这些：

尝试使用以下命令将 MATLAB 恢复到其默认搜索路径：

>>restoredefaultpath;
>>rehash toolboxcache;

现在尝试使用 contourf。如果可行，请保存路径设置，使用：

>>savepath; 

您需要自己将自定义文件夹添加回 MATLAB 路径，因为这会将 MATLAB 恢复为其默认路径设置。
