title: how to convert a double array to character string
body: <p>hello i have entered some text and convert it to the binary values.these binary values get stored in a array of data type double. Now i want to get the char array from that array containing binary values.</p>
  
  <pre><code>text2='hello how are u';
  text3=double(text2);
  nValues = numel(text3);
  B=8;
  bit_stream = zeros(1,nValues*B);
  % eight bit for binary representation of each character.
  for iBit = 1:B                    %# Loop over the bits
  bit_stream(iBit:B:end) = bitget(text3,B-iBit+1);  %# Get the bit values
  end
  bitstream=bit_stream;
  </code></pre>
  
  <p>how to perform vice-versa..</p>
