I wanted to elaborate on the title, but it's not easy, so I'll explain it with the following example.
For example, there is [1 434 22 434 23 53 89 199]
I want to change it to [1 7 2 7 3 4 5 6]
434 is 7th min value. 22 is 2nd min value.
I want to know what i th min value of the each value is, and it insert to the matrix.

Here you go..
A = [1 434 22 434 23 53 89 199];
newVector = [];
for i=1:length(A)
minimum = find(ismember(unique(A),A(i)));
newVector = [newVector, minimum];
end

This is the simplest:
v = [1 434 22 434 23 53 89 199]
[~, ~, newv] = unique(v)

A = [1 434 22 434 23 53 89 199];
u = unique(A)
for i=1:1:length(A)
A(find(A==u(i))) = i;
end
