It seems that clearing the command window (clc) is not possible in parfor. How do I achieve this then? I.e. i'd like this loop:
N=50;
parfor ii=1:N
rv=rand(1);
pause(rv)
clc
disp(rv)
end
To behave similarly to:
N=50;
for ii=1:N
rv=rand(1);
pause(rv)
clc
disp(rv)
end

The clc command does clear the command window of the worker it was run on, not the client session.
One possible workaround would be to use fprintf with \b to "erase" what you've done essentially updating the same few characters. However, I'm not sure the how the command window would react to multiple workers concurrently trying to access it.
