How to sort a 2-d array by the descending order of the other 1-d array?

Hi, all

   I have a 2-d array x(m,n) and a 1-d array y(m), and I want to sort the array of x
by the descending order of y.

For example, assume x(m,n) = (/ x(0,0),x(0,1), ...x(0,n-1)
                                             x(1,0),x(1,1), ...x(1,n-1)
                                             ...
                                             x(m-1,0),x(m-1,2) ... x(m-1,n-1)/)
and y(m) = (/y(0),y(1), ...y(m-1)/)

also assume y(1) is the max value of y , then is y(m-1) , and y(0) is the minimun value of y

I want the x(m,n) to be in order like these : x = (/ x(1,0),x(1,1) ,.....
                                                                      x(m-1,0),x(m-1,1) , ...
                                                                      ....
                                                                      x(0,0),x(0,1) , .... x(0,n-1)/)
How could I get it? Thanks a lot
