MATLAB: How to extract data from multiple Matlab figures

extract datafor loop

Hello everyone, I have extracted data from Matlab figure saved in “.fig” format by using the following code
   open F1.fig   %%F1.fig is the first figure
   D = get(gca, 'children') 
   x=get(D, 'xdata');
   y=get(D,'ydata');
   z=get(D,'cdata');
x, y, and z are the extracted data of x,y and z components.For only one case I have total 90 figures so by using the above code for each figure take much time. Now I need to use the above code for all 90 figures and get the data at once. I tried by using for loop but it does not work. Thanks

dinfo = dir('*.fig')
fignames = {dinfo.name};
numfig = length(fignames);
x = cell(numfig, 1);
y = cell(numfig, 1);
z = cell(numfig, 1);
for K = 1 : numfig
  figfile = fignames{K};
  try
    fig = openfig(figfile);
    ax = get(fig, 'CurrentAxes');
    if ~isempty(ax)
      D = get(ax, 'Children');
      x{K} = get(D, 'XData');
      y{K} = get(D, 'YData');
      z{K} = get(D, 'ZData');
    else
      fprintf('note: file "%s" has empty current axes\n', figfile);
    end
    close(fig);
  catch ME
     fprintf('note: file "%s" could not be opened as figure\n', figfile);
  end
end
