Run parallel function.

HI all,

I have one function with different input values

function chooseDirectionRolling(Coord,Arrow)
    for i=1:100
        doRolling(Coord,Arrow); %an example of other function
        Coord=Coord+i;
    end
end

I want to run this function for four direction at the same time, when I do as below, it takes times

chooseDirectionRolling(rightCoord,rightArrow);
chooseDirectionRolling(leftCoord,leftArrow);
chooseDirectionRolling(upCoord,upArrow);
chooseDirectionRolling(downCoord,downArrow);

Q: How can I run at the same time for one function with different input variables?

I tried to used parfor but it did not work.

I understand that, you want to execute four functions parallely.You may consider using parfeval.The syntax of parfeval is

F = parfeval(p,fcn,numout,in1,in2,…)

Please refer https://in.mathworks.com/help/parallel-computing/parallel.pool.parfeval.html for more information on parfeval.
