I believe this block

>      if k<10
>         eval(['print("' png_path 'snapshot_000' num2str(k) '.png",
> "-dpng");']); 
>       elseif k<100
>         eval(['print("' png_path 'snapshot_00' num2str(k) '.png",
> "-dpng");']); 
>       elseif k<1000
>         eval(['print("' png_path 'snapshot_0' num2str(k) '.png",
> "-dpng");']); 
>       else
>         eval(['print("' png_path 'snapshot_' num2str(k) '.png",
> "-dpng");']); 
>       end

can be replaced by

  print (sprintf ("%s/snapshot_%.5d.png", png_path, k));

but I haven't tested it, so it might need slight alterations. I
principle you should be using 'fullfile' concatenate the directory name
with the file name as that would give you platform independence, but I
didn't bother doing that here.
