@Akash Pal please clarify with a small example what you wish to happen. Is your main function calling another function which you wish to "cancel" after a certain period of time (if it hasn't completed)? If so, please describe the scenario as to why you would want to do this.

Thank you .
Let me clarify my programming details,
See i have a main function
function [ x , y , z, a, b ,c]=mainfun(in1 ,in2,...)
[x,y,z]=subfun1(input);
[a,b,c]=subfun2(input)
end
so ,my question is if i want to stop/cancel my subfun2 after 30 minutes ,because i know it will take too much time but i want to visualize the result of other sub function , then what to do ?

If you use parfeval() then you can cancel() the future.
However when you cancel a future you do not have access to its workspace. You cannot use this method to get "best results so far" from the worker.
If you create Parallel Data Queues then you can use them to send requests some kinds of workers. But this approach requires cooperation with the worker.
