MATLAB: Cannot fill table with chars

tables

Hi I am having a pile of issues with the table features in matlab.
I can't figure out how to put a char array into a char variable of a table. I've been reading the table help files but Il'm missing something 🙁
x=[1;2;3];
y=[4;5;6];
T=table(x,y)
T =
  3×2 table
    x    y
    _    _
    1    4
    2    5
    3    6
>> T.words = repmat({''}, 3, 1);
>>  T(1,'words') = 'poop';
The number of table variables in an assignment must match.
 
>> T(1,3) = 'poop';
The number of table variables in an assignment must match.
 
>> T{1,3} = 'poop';
The value on the right-hand side of the assignment has the wrong width. The assignment requires a value whose width is 1.

Best Answer

x=[1;2;3];
y=[4;5;6];
T=table(x,y);
T.words = repmat({''}, 3, 1); % this creates a 3x1 cell array
After these lines, T.words is a cell array:
>> T.words
ans =
  3×1 cell array
    {0×0 char}
    {0×0 char}
    {0×0 char}
You can fill it like so:
T(1,'words') = {'a'};
T(2,3) = {'bcd'};
T{3,3} = {'e':'z'};
% alternatively,
T{3,3}{1} = 'e':'z';
Which results in this:
>> T
T =
  3×3 table
    x    y             words          
    _    _    ________________________
    1    4    'a'                     
    2    5    'bcd'                   
    3    6    'efghijklmnopqrstuvwxyz'
