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
