Sort computations into groups in for loop

Hey guys, I was wondering if there is a way to group computations in a for loop. For example i have N set of training vectors, each vector has 2 values(2_Dimensional). All these vectors need to be subtracted from the two reconstruction vectors to find the distance between either reconstruction level. This is what I want, once the for loop computes the distance between both points, group that value into a group which consists of values that are all close to their respective reconstruction level. Thanks

Sure. Assuming all your training vectors are in rows of a 2D array, did you try something like this

for k = 1 : n
  % Extract the k'th training vector from the list of all of them.
  thisTrainingVector = allTrainingVectors(k, :); % Extract row
  % Get difference between this vector and the first "reconstruction vector".
  diff1 =  thisTrainingVector - reconstructionVector1;
  % Get difference between this vector and the second "reconstruction vector".
  diff2 = thisTrainingVector  - reconstructionVector2;
  % Then do whatever you need to do with diff1 and diff2.
end
