Why does winopen not work well?
显示 更早的评论
After ranning hundreds of lines of code and export for a mat table, code winopen the folder does not worked so well while busy is displayed at the botttom left corner? Even train sould has been player, the desired path is still not opened. If you only ran the cold winopen, it works well. I do not know why?
Does anybody know how to sovlve this? Appreciate for any help or any clue.
Belllow is the end of the code I have ran.
% omit of some code for processing
outputName = fullfile(path, ,'ResSal_Type.xlsx']);
writecell(Res, outputName, 'Sheet', 'Sheet1');
disp(sprintf('Finished'));
winopen(path)
load train % loads two variables, y and Fs
sound(y, Fs); % plays the sound

You wrote to file outputName but then try to only open the folder -- that will open file explorer to the given folder but clearly should NOT open the file, that isn't what winopen() was asked to do.
Use
...
winopen(outputName )
...
instead.

I'll note that if you try this for large (for system and phase of the moon dependent definitions of "large") numbers of files in a tight loop you're likely to hang and/or crash MATLAB, Excel, the system or any or all combinations of the above...

outputName = fullfile(path, ,'ResSal_Type.xlsx']);
Also NOTA BENE: there's a null element in the fullfile argument list -- that probably is not the intent.
See the Answer for this follow on.
As for the code as written not opening the folder, probably the dispatch of the sound player is hanging up a system call.
Try a short time delay for the event before moving on to play the sound or perhaps a couple drawnow calls might help...

Repeating previous comment in sequence so more likely to be found...
I wrote the following earlier in response to your other comment to other respondent--

To prove the above hypothesis, try commenting out the call to sound(y,FS) temporarily.
If the winopen() call then works as expected, it is the system sound call that is blocking the other OS system call. Unfortunately, it doesn't appear that sound is supported in the threaded functionality; one can hope that maybe a drawnow would let the system have a chance to dispatch the other code...

However, a trivial case here to try to illustrate seems to work...
winopen(cd)
load gong.mat;
sound(y);
A script containing only the above here works seemingly every time (warning--the gong is quite annoying if your speaker volume is set at any great magnitude...)
See if such a trivial case will work for you...if so, and your other code still doesn't, then it begins to look like something else not shown may be the culprit instead.
