running parpool parallel Matlab on cluster

I need to use parallel for Matlab running on cluster
I can run the Matlab code without problem on cluster with the .pbs file and get the display results



load CG_data;

trade = testdata(:,3);

day = testdata(:,1); 

clear testdata;



obs = size(trade,1);

nday = day(obs);



disp(nday)

disp(obs)


However, when I try to add the parallel to my code:



poolobj = parpool(6);

parfor (i = 1:6 )



load CG_data;

trade = testdata(:,3);

day = testdata(:,1); 

clear testdata;



obs = size(trade,1);

nday = day(obs);



disp(nday)

disp(obs)



end

delete(poolobj)


I will get error :
Starting parallel pool (parpool) using the 'local' profile ...
connected to 6 workers.
{Error using eval
Undefined function or variable 'testdata'.



Error in trial (line 2)
parfor (i = 1:6 )
}



It seems that after I run the parallel, I was not able to load data the same way when parallel was not set up in the environment.
Many many thanks!

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

          Trompette piccolo

          Ne doit pas être confondu avec trompette de poche. Trompette piccolo en si bémol, avec des branches d'embouchure différentes pour le si bémol (la plus courte) ou la (la plus longue) Trompette piccolo La trompette piccolo est la plus petite de la famille des trompettes. Elle joue une octave plus haut que la trompette standard en si bémol. La plupart des trompettes piccolo sont conçues pour jouer dans les deux tonalités de si bémol ou la, en utilisant une branche d'embouchure différente pour chaque tonalité. Le tube de la trompette piccolo en si bémol a une longueur moitié de celle de la trompette normale en si bémol. Des trompettes piccolo en sol, fa, ut sont également fabriquées, mais elles sont rares. La trompette soprano en ré, aussi connu comme la « trompette Bach », a été inventée vers 1890 par le facteur belge Victor-Charles Mahillon pour jouer les parties hautes de la trompette dans la musique de Bach et Haendel.
