Hello everyone !
I'd like to know how to sort the axial and radial coordinates of a range of points only by using the function "sort". For instance, if the row vector x=[3 2 1] matches with y=[4 5 6], I'd wish to obtain x=[1 2 3] and y=[6 5 4]. I specify I don't want to use another function than "sort" and I only work with row vectors.
Thanks a lot for your answers !

x=[3 2 1];
y=[4 5 6];
[xout,i1] = sort(x);
yout = y(i1);
or
xy = sortrows([x;y].',1).';
yout = xy(2,:);
