I have 2 cell array of string. The content of the cells is exactly the same, only the order is different.
I want to sort one, without changing the order of the other.

[tf, idx] = ismember(B,A);
Places where tf are false are places where B is not in A. And of course, B might not cover all of A. If you know that B covers exactly A, then B(idx) should be the same as A

ismember() is exactly what I needed. Thank you very much!

Your title and your description do not agree. Your description has a trivial answer ("just don't use the second variable") so I will answer based on your title;
[sortedvals, sortidx] = sort(FirstCell);
newCell = SecondCell(sortidx);

No they agree, I've not been clear. I've :
Vector A {'pierre'} {'paul'} {'jacques'}
Vector B {'jacques'} {'pierre'} {'paul'}
I want to get the index on how to reorder B to fit the order of A.
A first solution would be to sort both alphabetically, I could do that, but here the point is that I don't want to reorder A.
