How do I plot a temporary variable in a parfor loop?
显示 更早的评论
Hi,
I'm trying to make a surf plot with a parfor loop:
figure();
hold on
view(3)
[x,y,z]=sphere;
h=waitbar(0,'Please wait, generating figure');
for i=1:N
for r=linspace(.1,15,40) % sphere radius
clr=colormap(jet(N_unique));
h=surf(XFoci(i) + r*x,YFoci(i) + r*y,ZFoci(i) + r*z,'facecolor',clr(ic(i),:),'edgecolor','none');
alpha(h,(1./(r+1)));
end % for r=linspace(.1,10,40) % sphere radius
end % for i=1:N
Other than the fact that I have to change r to be integer numbers (no problems), I'm not sure how to parallelize the surf ploting using parfor.
Thanks, Guy

Unfortunately, parallel pool workers are separate MATLAB processes, and they cannot access the same figure handles that your desktop MATLAB client creates. Workers can create graphics, but each worker does so independently, so you cannot have multiple workers collaborate on a figure. After a worker has produced graphical output, the next step is to use print to output it to a file - workers cannot display graphics on-screen.
