MATLAB: Taking data points in between multiple interval times times and outputting them in separate structural arrays

arraybsxfunintervalsspike timesstructstructural array

I have spike times in one matrix. I then have time intervals, start and stop times, that I would like to get all the spike times in between. I believe I could use bsxfun and @ge function to do this, but I would like to have each interval of extracted spikes time outputted into separate structural arrays. The field names do not matter for the structural array and can be the same. I think I can use the struct function, but I have had issues on how to use these two functions in the way I want.
To sum, I have intervals, Start time and Stop time, in one matrix (intervals) and I want to get corresponding spike times (spiketimes) from each interval of another matrix and output them into individual structural arrays for each interval. I have attached example matrices of what the two matrices look like.

spiketimes=spiketimes'  % just to visualise horizontally
[sz1_intervals sz2_intervals]=size(intervals)
% init containers of variable length for found spikes within each interval
for k=1:1:sz1_intervals
     spk{k}={}
end
for k=1:1:sz1_intervals
     w=intervals(k,:);
     spk{k}=intersect(spiketimes(find(spiketimes>=w(1))),spiketimes(find(spiketimes<=w(2))));
end
each group of spikes is contained in respective cells:
spk{1}
 =
=
  Columns 1 through 5
         60.18         60.18         60.18         60.18         60.18
  Columns 6 through 10
         60.18         60.19         60.19         60.19         60.19
..
         64.93         64.93         64.94         64.94         65.02
  Columns 81 through 84
         65.02         65.02         65.04         65.05
