Error using cd Cannot CD to ...(Name is nonexistent or not a directory)
显示 更早的评论
Hi,
I have the following code
oldp = uicontrol(fig,...
'Style', 'Push',...
'BackgroundColor', [1 1 .7],...
'units', 'normalize',...
'Position', [0 .333 1 .333],...
'String', 'Open an existing Project',...
'Callback', [...
' [projfile,projpath] = uigetfile(''*.prj'',''Select Project File '');',...
' cd(projpath);',...
' load(projfile,''cp'',''-mat'');',...
' close(gcf);',...
' clear projpath projfile newp oldp stringforhelp ui*; '...
]...
);
I am getting this error:
Error using cd
Cannot CD to C:\...(Name is nonexistent or not a directory)
Any idea? thanks

Do NOT define the callback as a character vector. The MATLAB documentation
states "Defining a callback as a character vector is not recommended". Specifying the callback with a function handle is recommended, and will make debugging your code much easier.
Do NOT use cd just to read/write data files. All MATLAB functions that read/write data files accept absolute/relative filenames: you should use fullfile to generate the absolute/relative filename and pass that to load (or whatever function you use for reading/writing data files).
Using clear is rarely required in code, and is almost always overused by beginners.

Hi,
You can write the following lines in your callback function:
[projfile,projpath] = uigetfile('*.prj','Select Project File ');
abs_filepath = fullfile(projpath,projfile);
load(abs_filepath,'cp','-mat');
Hope this helps!
