在 MATLAB Online 中打开

You can test it in Matlab windows command

% If your current forlder is D:\a\b, after
cd('../')   
The current folder will be D:\a

The same with pwd

pwd % gives you the current folder

Hi farzad,

The first line, MatDir=pwd; is simply setting the local variable MatDir to the current working directory. Try typing this at the MATLAB command window, and also type help pwd for more details on this command.

The second line, cd('../') simply changes the current working directory to one level above that. Again, from the MATLAB command window, try this command and then re-type pwd. Also, to look for help on this and other commands, just type help cd.

Note that these two commands aren't specific to MATLAB in any way…
