MATLAB: Combined sorting

paired sorting

For ex;I have an array A=[1:4] and B=[12:19:2:20].If I sort B in descending order B=[20 19 12 2].I want the corresponding positions in A to be swapped as well…ie A=[4 2 1 3].How do I achieve that?

Best Answer

  • [sortB,idx] = sort(B,'descend');
    sortA = A(idx);
    Or put the vectors into a matrix and use sortrows.
