Extract variable from function after using parfeval

I am running the following:
fcn=@(i) run("test"+i);
for K=1:4
F(K)=parfeval(fcn,0,K);
end;
where "test"+i is a script solving to pricude results in matrix format.
I would like to be able to see this matrix after the worker has finished.
I have tried setting the cript as a fucntion and having an outout:
function [Result1]= test1
however I still get no data out of this after using fetchOutputs.
How can i get the variable I require after parfeval has finished?

@Koren Murphy the issue is that you've told MATLAB there are no output arguments (even if there are)
F(K)=parfeval(fcn,0,K);
The "0" is the number of output arguments. Change this appropriately. For instance
for idx = 1:10
f(idx) = parfeval(@rand,1,idx);
end
% Now fetch the results
for idx = 1:10
[idx, value] = fetchNext(f);
R{idx} = value;
end

The run command doesn't return any outputs. Presumable this is a test example. Replace it with the function you're going to actually run.
