Hello there,
I have data witht the first column being the year and the second column being the rainfall. I would like to sort the data from largest rainfall to smallest while keeping the associated years the same. I have tried using the Sort function of exactly how to do this.
Any help is appreciated,
Thanks,
Brian

Use sortrows, e.g. where M is your matrix:
M = sortrows(M,2);
If you really want to use sort, then of course you will need to use indexing, e.g.:
[~,idx] = sort(M(:,2));
M = M(idx,:);
