How can I get multiple for loops to run at the same time?

%Points
P1=[-15,0];
P2=[-5,0];
plot([P1(1) P2(1)],[P1(2) P2(2)],'LineWidth',5,'Color','black');

A=[0,0];
circle=viscircles(A,5,'LineWidth',2,'Color','black');

pause(.5)

%Circle B
for b=0:pi/80:pi/8;
    pause(.5)
    B=A+[10*cos((-pi/8)+b), 10*sin((-pi/8)+b)];
    circle2=viscircles(B,5,'LineWidth',2,'Color','green');
end

%Circle C
for c=0:pi/40:pi/4;
    pause(.5)
    C=B+[10*cos(-(pi/4)+c), 10*sin(-(pi/4)+c)];
    circle3=viscircles(C,5,'LineWidth',2,'Color','blue');
end

To get them to run at the same time, you have to run them on separtae CPU cores. To do that you need to use parfor (instead of for), which is in the Parallel Processing Toolbox.
