Sort Data by Second Column

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,:);
