Ranking values - sorting into descending order

I have a that for each row (i) ranks the column values. However, it ranks them in the ascending order. I require it to be ranked in descending order. Can anyone help with modifying the below code block to descending order?

for i = 1:height(d)
    [temp, ranked]  = ismember(X(i,:),unique(X(i,:)));
    rnkR1List(i,:) = ranked;
end

If you do not expect there to be duplicates, I too recommend to use sort instead.

[~, rnkR1List] = sort(X, 2, 'descend');

If you absolutely need identical values to have the same ranks, then you could extend your own code by just inverting the ranks:

for i = 1:height(d)
    [temp, ranked]  = ismember(X(i,:),unique(X(i,:)));
    rnkR1List(i,:) = ranked;
end
max(rnkR1List, [], 2) - rnkR1List + 1;

Just use the Matlab function sort without any looping. See an example below.

X = randn(10, 10);
Xranked = sort(X, 2, 'descend');
