MATLAB: Inserting a 1000 separator

1000 separatorformattext;

Hi, I am building a table in which I need to insert numbers with a comman 1000 separator and two decimal points. For example: A=11201453.21 % should be A=1,1201,453.21 Any hint about how to do it? Best,

Here's a function I've used:
%=====================================================================
% Takes a number and inserts commas for the thousands separators.
function [commaFormattedString] = CommaFormat(value)
  % Split into integer part and fractional part.
  [integerPart, decimalPart]=strtok(num2str(value),'.'); 
  % Reverse the integer-part string.
  integerPart=integerPart(end:-1:1); 
  % Insert commas every third entry.
  integerPart=[sscanf(integerPart,'%c',[3,inf])' ... 
      repmat(',',ceil(length(integerPart)/3),1)]'; 
  integerPart=integerPart(:)'; 
  % Strip off any trailing commas.
  integerPart=deblank(integerPart(1:(end-1)));
  % Piece the integer part and fractional part back together again.
  commaFormattedString = [integerPart(end:-1:1) decimalPart];
  return; % CommaFormat
