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.

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
