I couldn't remember the function to check if a directory exists so I typed the following, and then accepted the suggested correction:
>> ispath('plots')Unrecognized function or variable 'ispath'. Did you mean:>> path('plots')Warning: Name is nonexistent or not a directory: /Users/billtubbs/gel-2005/notes/10/plots > In path (line 34) com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.com.mathworks.jmi.MatlabException: Method 'workspaceUpdated' is not defined for class 'internal.matlab.variableeditor.MLNamedVariableObserver' or is removed from MATLAB's search path.
Now I get these errors whatever command I type (including path). I can't even quit MATLAB.
How do I recover from this situation?
Ideally I would like to restore whatever paths I had set up before typing the above command.
