Error using subplot (line 301) Index exceeds number of subplots.

ax = gobjects(imageset.Count,1);
for ii =  1:imageset.Count
  ax(ii) = ...
  subplot(floor(sqrt(imageset.Count)),ceil(sqrt(imageset.Count)),ii);          %Error show me on this line

end
expandAxes(ax);

The error message is straightforward.

Your ‘ii’ index is greater than floor(sqrt(imageset.Count)) * ceil(sqrt(imageset.Count)).

>> t = 1:100;
>> find(floor(sqrt(t)).*ceil(sqrt(t)) < t)

ans =

  Columns 1 through 25

     3     7     8    13    14    15    21    22    23    24    31    32    33    34    35    43    44    45    46    47    48    57    58    59    60

  Columns 26 through 45

    61    62    63    73    74    75    76    77    78    79    80    91    92    93    94    95    96    97    98    99

For example, suppose the Count is 8, then sqrt(8) is between 2 and 3, so the floor() is 2 and ceil() is 3, and 2*3 = 6, which is less than 8, so when you tried to plot for the 7th you would run out of subplots.
