Is this what you're after?
vector = [4 1 6 9 2 1 8 3];
[sorted,sortinds] = sort(vector)
sorted =
1 1 2 3 4 6 8 9
sortinds =
2 6 5 8 1 3 7 4
Here, sortinds gives the locations of the sorted values in the original vector vector, e.g., the first element in the sorted vector is 1=vector(2), the second is 1=vector(6), the third is 2=vector(5), etc.
