May i know why do i keep getting this error > ??? Index exceeds matrix dimensions.

Previously im using

>> plot(delta_diff(110:870,490),'XData',[0:(D*1000)/760:(D*1000)])

and it was working fine. but once i changed the range as below. it start to give me error.

Error in ==> four_step_polarimetry at 86
plot(delta_diff(230:990,610),'XData',[0:(D*1000)/760:(D*1000)])
   figure
  plot(delta_diff(230:990,610),'XData',[0:(D*1000)/760:(D*1000)]);  
  title('Plotting of Delta (No Residual Stress)')
  xlabel('Distance(mm)');
  ylabel('Delta(3kg)');
  figure_FontSize=12;
  set(get(gca,'XLabel'),'FontSize',figure_FontSize,'Vertical','top');
  set(get(gca,'YLabel'),'FontSize',figure_FontSize,'Vertical','middle');
  set(findobj('FontSize',10),'FontSize',figure_FontSize);
  set(gca,'tickdir','in')
  set(gca,'ticklength',[0.01 0.01]);
  axis on

i uploaded the script for your reference. below was the commands before the error

    delta = imfilter(delta,h); 
delta_diff =delta - o_delta; 
figure;imshow(delta,[0,0.6]);axis off,colorbar
colormap(jet)
axis on
figure;imshow(delta_diff,[]);axis off,colorbar
colormap(jet)
axis on

We are not given information about the sizes of the images, so we cannot calculate the sizes of delta_diff . It would be much easier if you were to tell us what the size of delta_diff is... as well as teling us why column 610 exactly should be the one that is to be used.
