Given two numeric inputs a and b, return a row vector that contains the numbers found in only a or only b, but not both. For example, the inputs:

a=[1 2 3 4 5];

b=[2 3 4 5 6];

would return [1 6], as 2, 3, 4 and 5 are in both a and b, and can therefore be eliminated. Please sort the returned vector in order from lowest to highest.

You may assume that there is at least one value that meets these criteria in a or b, and there are no NaN or Inf values in either a or b.
