MATLAB: How to give ranking from highest to lowest

Control System Toolboxranking elements

Hello, I have number like

Data=[5 6 9 1 5 2]

I want to rank them as: [3 2 1 6 4 5] Can any please help me How can I do this. Thanks in advance.

This should give you the rank you are asking for, Mekala:

   [~,p] = sort(Data,'descend');
   r = 1:length(Data);
   r(p) = r;

'r' will be the ranking.

unique(cell2mat(A))

I assume, the result should be [2 4; 5 6; 3 1] with the last two elements swapped. The method is called sorting, not ranking.

M = [1,5; 7 9; 2 0];
[dummy, index] = sort(M(:));
R(index) = 1:numel(M);
R = reshape(R, size(M));
