MATLAB: Remove repeated values in a CSV string

csv stringremove duplicates/string

I have a string with comma separated values, and would like to delete the repeated values so that there are no repeats in my string.
mystring = '1,1,1,25,33,33,5,5,3,2,1,1'
Iwant = '1,25,33,5,3,2'
The order of the numbers in "Iwant" is not important. It could be '1,25,33,5,3,2' or "1,33,5,25,3,2" or "2,3,5,33,1,25" (whatever works).
I have many other strings I would like to edit, so it would be great if the code could apply to a string with any manner of numbers in it.

mystring = '1,1,1,25,33,33,5,5,3,2,1,1' 
iwant = join(unique(split(string(mystring),',')),',')
results in a string:
mystring =
    '1,1,1,25,33,33,5,5,3,2,1,1'
iwant = 
    "1,2,25,3,33,5"
Note, that you speak of string, but use char type. if you want char as result use this instead:
iwant = char(join(unique(split(string(mystring),',')),','))
