MATLAB: Who to sort pairs of arrays in the same order one based on the other

Question

Hello MATLAB experts, I have asked many questions and I really appreciate your prompt responses. My New question is that, I have set of pairs of arrays. In each pair, one array has numbers from 0 to 20 (but not arranged) for one variable values and the other array have decimal values presents the other variable values. I want to sort the elements in the first array in ascending order (0,1,2,…20) but at the same time I want to sort the other accompanied array of the pair in the same order (indices sorted similarly).

Answer 1

[firstsordered, firstsortorder] = sort(first_array);
secondsorted = second_array(firstsortorder);
