How to find the nearest points to given coordinates with MATLAB?

Question

I need to solve a minimization problem with Matlab and I\'m wondering which is the easiest solution. All the potential solutions that I\'ve been thinking in require lot of p

Answer 1

Let Lat and Long denote latitude and longitude matrices, then

dist2=sum(bsxfun(@minus, cat(3,A,B), cat(3,Lat,Long)).^2,3);
[I,J]=find(dist2==min(dist2(:)));

I and J contain the indices in A and B that correspond to nearest point. Note that if there are multiple answers, I and J will not be scalar values, but vectors.
