Finding Indices of Duplicate Values to create a new array

Hi all, I have this data and would like to find the unique regions and create a new dataset for the Score for the various unique regions, I have looked at the matlab unique function but I am still unsure. Your help will be greatly appreciated.

Happiness_Score = [7.587,7.561,7.527,7.522,7.427,7.406,7.378,7.364,7.286,7.284,7.278,7.226,7.2,7.187,7.119,6.983,6.946,6.94,6.937,6.901,6.867,6.853,6.81,6.798,6.786,6.75,6.67,6.611,6.575,6.574,6.505,6.485,6.477,6.455,6.411,6.329,6.302,6.298,6.295,6.269,6.168,6.13,6.123,6.003,5.995,5.987,5.984,5.975,5.96,5.948,5.89,5.889,5.878,5.855,5.848,5.833,5.828,5.824,5.813,5.791,5.77,5.759,5.754,5.716,5.709,5.695,5.689,5.605,5.589,5.548,5.477,5.474,5.429,5.399,5.36,5.332,5.286,5.268,5.253,5.212,5.194,5.192,5.192,5.14,5.129,5.124,5.123,5.102,5.098,5.073,5.057,5.013,5.007,4.971,4.959,4.949,4.898,4.885,4.876,4.874,4.867,4.857,4.839,4.8,4.788,4.786,4.739,4.715,4.694,4.686,4.681,4.677,4.642,4.633,4.61,4.571,4.565,4.55,4.518,4.517,4.514,4.512,4.507,4.436,4.419,4.369,4.35,4.332,4.307,4.297,4.292,4.271,4.252,4.218,4.194,4.077,4.033,3.995,3.989,3.956,3.931,3.904,3.896,3.845,3.819,3.781,3.681,3.678,3.667,3.656,3.655,3.587,3.575,3.465,3.34,3.006,2.905,];
