multiple subplots in a figure

I am trying to plot multiple subplots in a single figure. But some weired problem exists and some subplots are deleted !! or maybe there exists other methods to add multiple subplots.

nx=20; ny=10;
ngrids=nx*ny;
figure;
for i=1:ngrids
    y=ceil((i)/nx);
    x=i-(y-1)*nx;
    subplot(nx,ny,i);
    axis square;
    set(gca,'xtick',[],'ytick',[],'Position', [((-1/nx)+x/nx) ((1-1/ny)-(y-1)/ny) (1/nx) (1/ny)]);
    text(.5,.5,int2str(i),'FontSize',9,'HorizontalAlignment','center')
    pause(0.001);
end

Main point there -> use "axes" instead of "subplot" if you are going to modify the position manually anyway.

nx=20; 
ny=10; 
ngrids=nx*ny; 
figure; 
for i=1:ngrids 
    y=ceil((i)/nx); 
    x=i-(y-1)*nx; 
    axes
    axis square; 
    set(gca,'xtick',[],'ytick',[],'Position', [((-1/nx)+x/nx) ((1-1/ny)-(y-1)/ny) (1/nx) (1/ny)]); 
    text(.5,.5,int2str(i),'FontSize',9,'HorizontalAlignment','center') 
    pause(0.001); 
end
