tiedrank in descending order?

Is there any way to use tiedrank in descending order? I need to rank the highest value as the smallest one in rank. Is it possible to do this using tiedrank or another built-in-function? Thank you~~

To do this in one line, just negate the vector. For example:

>> counts = [23, 1, 17, 95, 133];
>> ranks = tiedrank(-counts);

>> ranks
ranks =
     3     5     4     2     1

Hi Ekin,

You can the reverse the order of ranking programmatically as follows:

 %Store the result of tiredrank function in "a"
a = tiedrank([10 20 30 40 20]);
%Find the largest rank value of "a", increment it by 1 and subtract "a" by
%this value.
ranks_desc = (max(a)+1) - a;

This will just reverse the ranking received by "tiedrank" function.
