MATLAB: How to add variables into a string within a table

MATLAB

I have a table with a column of 10 digit strings that I need to add "-" into.
How do I turn a column of strings looking like this "0001336363" into a column of strings looking like this "0001336-36-3"?

  • The only option appears to be to turn the string variable into a char array first: 
    str = "0001336363";
    strc = char(str);
    Out = sprintf("%7s-%2s-%s", strc(1:7),strc(8:9),strc(10))
    producing: 
    Out = 
        "0001336-36-3"
    .
