I want to convert this string of binary message=110110111000011110010110100111000011101101 (1x42 char) to double array not cells (1x42)double but everytime I use the casteing double(message) I get string of 49 49 49 48 48 ... Ps;message was originally text and I translated it using dec2bin. Please help

Hi Mariam,
To convert string array to double array, compare it with character '1' and convert to double
logicalMessage = message == '1';
doubleArray = double(logicalMessage);
Hope this helps.
Regards,
Sriram

The sequence is not double and should not be converted to double.
char(bin2dec(reshape(message, 7,6).').')
The conversion to binary was faulty: the dec2bin() call should have had the second parameter 8 instead of no second parameter. If that were corrected then the 7 in my code would change to 8
