Stop an infinit function that is running in parallel with the remaining code, and get the outputs

Hello everyone,

I am looking for a way to retrieve the output of a function that is running in parallel (with the function parfeval for example) and that can run indefinitely if we don't stop it in the remaining code.

For example : This could be the function :

function a = infinit()
    go = true ;
    while go 
        a = 1 ; 
    end 
end

and this is the code :

parpool(1) ; 
f = parfeval(@infinit,1) ; 

% looking for the code line that can stop the function,  

value = fetchOutputs(f) ; 

I know that "cancel" can actually stop, but then we can't get the output. I have also tryed by using a global variable, or a public variable with app designer, but both of those way are not working. From my research so far, it seems there is no solution. But still I hope that someone has maybe found an idea ! ;)

Otherwise, I actually want to run a function in app designer that is reading data from a sensor periodically. Meanwhile the code is doing something else until the user has finished the experiment. Then I want to get the data from the function. I guess maybe there might be a workaround ?

I thank you all in advance for your help !

Thomas
