I was wondering if there was a way to combine a char array and a matrix

I have this character array

MwC =
  9×1 char array
    'w'
    'b'
    'y'
    'b'
    'w'
    'r'
    'y'
    'r'
    'b'

and this matrix

    newcoords =
     1
     2
     3
     4
     5
     6
     7
     8
     9

I have tried something like [newcoords, MwC] but that does not work and it outputs weird symbols

I need to be able to do something like

combined(1,2)= 'w'

I am ok with changing 'w' into a variable if that would work better

Your desired output is not clear.

 MwC = [
    'w'
    'b'
    'y'
    'b'
    'w'
    'r'
    'y'
    'r'
    'b'];
  newcoords = (1:9).';
  
  newcoords + string(MwC)
ans = 9×1 string array
    "1w"
    "2b"
    "3y"
    "4b"
    "5w"
    "6r"
    "7y"
    "8r"
    "9b"
  
  compose('%d %s', newcoords, MwC)
ans = 9x1 cell array
    {'1 w'}
    {'2 b'}
    {'3 y'}
    {'4 b'}
    {'5 w'}
    {'6 r'}
    {'7 y'}
    {'8 r'}
    {'9 b'}
  char(ans)
ans = 9x3 char array
    '1 w'
    '2 b'
    '3 y'
    '4 b'
    '5 w'
    '6 r'
    '7 y'
    '8 r'
    '9 b'
  compose("%d %s", newcoords, MwC)
ans = 9×1 string array
    "1 w"
    "2 b"
    "3 y"
    "4 b"
    "5 w"
    "6 r"
    "7 y"
    "8 r"
    "9 b"
  table(newcoords, MwC)
ans = 9x2 table
    newcoords    MwC
    _________    ___

        1         w 
        2         b 
        3         y 
        4         b 
        5         w 
        6         r 
        7         y
