MATLAB: Inserting one character many times into a string

insert characterstringstrings

I have a string with a bunch of words separated by commas

S='Apples,Oranges,January,February,…'

I get a vector with the placement of all the commas with

commas=strfind(s,',');

how do i place a character before every comma in the string, so it will come out like

Snew='Apples2,Oranges2,January2,February2,…'

You can simply use strrep:

>> S = 'Apples,Oranges,January,February,...';
>> strrep(S,',','2,')
ans = Apples2,Oranges2,January2,February2,...

test = table();

test.month = 'JANUARY';

test.month = lower(test.month); %writes it in lower case letters

or you can as well just replace it by your desired input

test.month = 'january';

P.S. You do not have a string but a character (char)

A = 'abc (ABC)';
B = regexp(A,'^\w+','once','match')
B = 'abc'
