What is the largest character array that MATLAB can hold?

What is the largest character array (i.e. string) that MATLAB can hold? Or, is it just a matter of computer memory?

Thanks!

You may have to wait for a while ....

% Don't try this at home ...
c = '' ;
try
  while(1)
     c = [c 'x'] ; % increase the string
    pause(0.001) ; % allow for Ctrl-C
  end
catch
  disp(length(c)) ;
end

Type memory at the command line and see what it says is the largest
array in terms of megabytes.

Theoretically, look at the second output of the COMPUTER function.

Practically, yes, in most circumstances the limit is a matter of how large a
contiguous block of memory you have available for storing the string.
