vector of integers modification

5 次查看(过去 30 天)
I have vector of positive integers which I need to modify into vector of consecutive integers with the same ordering.
Example:
rank = [4 1 2 2 4] -> rank_new = [3 1 2 2 3]

There are so many functions in matlab that it can be difficult not to shadow one. If you're not doing matrix algebra it doesn't really matter if you stomp on rank.
On the other hand, rank is not a particularly good variable name. rank of what? It would be much better if that what was added to the variable name.

Of course, you are right! I just use rank variable name by my mistake... :)

Possibly:
rank = [4, 1, 2, 2, 4];
[~, ~, rank_new] = unique(rank)
