Performing a loop of data structure array

Hi, I have a database named 'data' which contains 1x4 structure array.

I want to make a loop that replace the number of the data incrementally by 1. That is firstly i want to read from data 1, then data 2 ie n=1, m=2.for the next cycle it will read data 2 and data 3 ie n=2, m=3, and lastly n=3, m=4. I've try these command but the output is wrong.Please help me.

for n = 1:1:3

 for m = n+1:1:4
  index_L=matchFeatures(data(n).fL,data(m).fL);

   match1=data(n).vptsL(index_L(:,1));
   match2=data(m).vptsL(index_L(:,2));
   gte = vision.GeometricTransformEstimator; % defaults to RANSAC
   gte.Transform = 'Nonreflective similarity';
   gte.NumRandomSamplingsMethod = 'Desired confidence';
   gte.MaximumRandomSamples = 1000;
   gte.DesiredConfidence = 99.8;

   [tform_matrix inlierIdx] = step(gte, match2.Location, ...
   match1.Location);
   cvexShowMatches(data(n).imgL,data(m).imgL,match1(inlierIdx),...
   match2(inlierIdx),'ptsLeft1','ptsLeft2');
 end
end

Only use one for loop.

 for n = 1:1:3
  m = n + 1;
  ... code 
 end
