fill() in parfor loop
显示 更早的评论
I've got ~200,000 polygons to be plotted with fill().
for i=1:size(data,1);
x=data(i,3:2:9);
y=data(i,4:2:10);
f=fill(x,y,data(i,2));
hold on;
end
It works well but takes a bit of time. When I use 'matlabpool open local 4' and change 'for' to 'parfor', I've got no figure output. Any solutions please?

Do you actually expect to be able to differentiate 200000 polygons?

Hi,
you should be able to call fill with the corresponding matrices directly, something like
f = fill(data(:, 3:2:9)', data(:, 4:2:10)', data(:,2)');

Unfortunately, you cannot use a PARFOR loop in this way. The workers cannot create graphics on your client.
