Ho are you everyone !
I have this string :

ss=[2 3 4 5 1 2 6 7 5 3 2], what is the proper function for this purpose? Thank you a lot for any answer

Remove repetitions, return a string:
>> str = '222223444451111122666677775555533332222';
>> new = str([true,diff(+str)~=0])
new =
23451267532
It is easy to convert the string into a numeric vector of the digits:
>> vec = new-'0'
vec =
     2     3     4     5     1     2     6     7     5     3     2
