I am trying to execute a loop and getting this error how can i get out of it
% distanceOfAllNearestTargets = zeros(numberOfNearestNeighbors, 1);
locationNumberOfAllNearestTargets = zeros(numberOfNearestNeighbors, 1);
for ii = 1 : 1 : numberOfNearestNeighbors
locationNumberOfAllNearestTargets(ii, 1) = find(distanceOfAllTargetsFromCurrentPosition == min(distanceOfAllTargetsFromCurrentPosition));
distanceOfAllNearestTargets(ii, 1) = distanceOfAllTargetsFromCurrentPosition(locationNumberOfAllNearestTargets(ii));
distanceOfAllTargetsFromCurrentPosition(locationNumberOfAllNearestTargets(ii, 1)) = max(distanceOfAllTargetsFromCurrentPosition);
end

@madhan Ravi, I have a quite complex code it is just a function of that code.in which I need to generate an array of distances equal to a number of nearest target

find is not guaranteed to result 1 value. It might return a vector, or an empty array. If you are certain there will always be 1 result or more, you can use the later inputs to find to limit the results it returns to either the first one or the last one. If that doesn't fit your situation, you should store the find result in a temporary variable and use switch (or if) to handle the three cases (so numel(temp_result)==0, >1, and ==1).
locationNumberOfAllNearestTargets(ii, 1) = find(distanceOfAllTargetsFromCurrentPosition == min(distanceOfAllTargetsFromCurrentPosition),1,'first');

Try to make a small example that reproduces your error. You can attach a mat file with the actual data to your comment if you can't figure out a way to generate some example data.
