Hi there,
I have a dataset:
10 11 5 6 23 4 1 3 98 56
I want to find the 3 smallest values that exist in the dataset without replacing data from the original dataset as well their indices.
final result would be: Row,Value 7,1 8,3 6,4

[a,b] = unique(s,'first');

Alternatively you can sort them in ascending order and pick first three..
[val,pos] = sort(yourVector)
