I understood, convert the each character of the input string(usertext) to 0/1 if the ASCII value greater than 95 then i would be 0, if less than 95 then i would be 1, after this store the result to cell array
usertext = input('Enter your text message :','s');
binary = cellstr(num2str(double(usertext) < 95));
Hope I came up with your requirement !!
