MATLAB: create a list/cell array of strings

Question

data = {};
data(1) = 'hello';

gives this error Conversion to cell from char is not possible.

my strings are created inside a loop and they are of various lengths. How do I store them in a cell array or list?

`data{1} = 'hello'`. Use curly braces to refer to the _content_ of a cell — Luis Mendo, May 15 '15 at 16:55
@LuisMendo Yes! It works. If you post this as an answer I will accept it. — Sounak, May 15 '15 at 16:57

I believe that the syntax you want is the following:

data = {};
data{1} = 'hello';

Use curly braces to refer to the contents of a cell:

data{1} = 'hello'; %// assign a string as contents of the cell

The notation data(1) refers to the cell itself, not to its contents. So you could also use (but it's unnecessarily cumbersome here):

data(1) = {'hello'}; %// assign a cell to a cell

More information about indexing into cell arrays can be found here.
