Hi I have this array of numbers [5 5 6 6 6 11 11 ]and would like to convert every unique number from 1 to n. For example, if there are 10 unique numbers, I would like to relabel them from 1 to 10, with the same number coded the same for eg [1 1 2 2 2 3 3]
The actual array is attached here. How may I code for this? Thanks so much!

The simple and efficient MATLAB solution:
X = [5,5,6,6,6,11,11];
[~,~,Z] = unique(X,'stable')

data=[5 5 6 6 6 11 11];
counts=histc(data,unique(data));
data_result=repelem(1:length(unique(data)),counts)
Results:
data_result =
