Hi, in my program I have an array d, which is 100x1 and I have another 100x1 array e, that corresponds to d. I would like help to sort d in ascending order (d=sort(d);) and also change the positions of the elements in e such that the result still corresponds to the element positions in d. For instance if the smallest value in d is the fourth element it becomes the first element in d and the forth element in e changes position with the first element. Thanks.

Use the second return value of sort to reorder your e array.

[d, order] = sort(d);
e = e(order);

You can simply sort ‘e’ as well:

d = sort(d);
e = sort(e);

This assumes of course that all of the elements of ‘d’ are greater than zero.

thanks, if I have another array f that also corresponds to d but the magnitude of the values do not increase in the same way as the elements in d is there a way of changing the order to also correspond to d?
