Indicate a new quiver for each lopp

Hi I'm writing the code below and I'm wondering and I'm going to ask! I want to show a new quiver for each loop, but what do I need to change?

for q = 1:2:length(str2num) 
    a = char(str2num(q)) 
    b = char(str2num(q+1))
    imagea = imread(a)
    imageb = imread(b)
    size(imagea);
    size(imageb);
    for i=1:(w_xcount)
        for j=1:(w_ycount)
            max_correlation=0;
            test_xmin=xgrid(i)-w_width/2;
            test_xmax=xgrid(i)+w_width/2;
            test_ymin=ygrid(j)-w_height/2;
            test_ymax=ygrid(j)+w_height/2;
            
            x_disp=0;
            y_disp=0;
            
            test_ima=imagea(test_xmin:test_xmax,test_ymin:test_ymax);
            test_imb=imageb((test_xmin-x_disp_max):(test_xmax+x_disp_max),(test_ymin-y_disp_max):(test_ymax+y_disp_max));
            correlation=normxcorr2(test_ima,test_imb);
            [xpeak,ypeak]=find(correlation==max(correlation(:)));
            
            %re-scaling
            xpeak1=test_xmin+xpeak-wsize(1)/2-x_disp_max;
            ypeak1=test_ymin+ypeak-wsize(2)/2-y_disp_max;
            dpx(i,j)= xpeak1-xgrid(i);
            dpy(i,j)= ypeak1-ygrid(j);
        end
        quiver(-dpx,dpy)
    end 
end

....
  quiver(-dpx,dpy); hold on
  end
 end
 hold off

Can I get it to come up on a different screen???

And thanks for the answers!!!

You can direct the plot to appear in the axis "ax" of your choice with the syntax,

quiver(ax,___)

Or, perhaps,

....
   figure; quiver(-dpx,dpy); 
  end
 end
