Want to programmatically get the Maltlab status of (ready, busy), etc., in the bottom left corner of the window. What procedure will be used?

It's framed in red in the bottom left corner of the window.

[Jonas]

as soon as you want to get the state programmatically, you may get the busy state? or do you want to take this place in the background?

[BN]

Because my program runs for a long time, get status. I just want to know if the program is running properly.

[Jonas]

i would gueaa just asking for the busy state does not tell you if the programm is running properly. I experienced it multiple times, that matlab is busy, but it did nothing and the program hanged. if you want a more reliable way of telling if there is progress, you can write some status messages now and then using e.g. disp(). you can include there the time of displaying the message and maybe the progression, e.g. a loop variable and total nummber of loops

[Hornett]

When a program is executing, the command window displays a status text of 'Busy'. However, this status update does not occur during the execution of a timer object's callback. Thus, the presence of status text can indicate Matlab's activity state. CmdWinTool infers Matlab is occupied whenever the status text is present, a condition that also arises if execution halts during debugging.

Check this FEX: CmdWinTool: https://www.mathworks.com/matlabcentral/fileexchange/32005-cmdwintool

isBusy = CmdWinTool('isBusy')

I recommend you use waitbar() function as an indicator of the progress within the code.

f = waitbar(0,'Program started...');
%%% SOME CODE
waitbar(.2,f,'Uploading data ...');
%%% SOME CODE
waitbar(.5,f,'Post processing data ...');
%%% SOME MORE CODE
waitbar(0.9,f,'Generating report ...');
%%% Final codes CODE
waitbar(1,f,'DONE!');
close(f)
