What does it mean: fileStream​::DetectCh​arset():fr​ea ?

Hi, I'm using MATLAB Parallel Computing Toolbox to run a rather complicated project and I'm using parprogress to monitor the progress of the script. However, I see the following output and I don't understand the meaning of it:

fileStream::DetectCharset():frea

Does anyone know? Thanks!

Here's a trivial example. Look at the documentation for more information.

function zw

d = parallel.pool.DataQueue;
d.afterEach(@giveUpdate)

parfor idx = 1:20
    A(idx) = rand;
    send(d,idx)
end
end

function giveUpdate(varargin)

fprintf("Finished simulation " + varargin{:} + "\n")
end

Thank you very much!

Can't answer this for you, but you might consider looking at DataQueues https://www.mathworks.com/help/parallel-computing/parallel.pool.dataqueue.html so another solution.

Thank you. Not sure if I understood you correctly, are you suggesting another solution to monitor the progress of parfor?
