s = 'Mary had a little lamb';
binary = dec2bin(s);
str = bin2dec(binary)

but str i obtained is not string... how to get the string back... also, when i do above i get binary as char variable...

is it possible, to get is as a vector, with double datatype and i should be able to get that back as string...

binary =
1  1  0  1  0  0  0  0  1  0

binary = reshape(dec2bin(s, 8).'-'0',1,[])
str = char(bin2dec(reshape(char(binary+'0'), 8,[]).'))

@Walter Roberson how these two lines are working? I only understand dec2bin and bin2dec.

@Awais Saeed

s = 'Awais Saeed';

binary = reshape(dec2bin(s, 8).'-'0',1,[]);

display(binary);

str = char(bin2dec(reshape(char(binary+'0'), 8,[]).'));

display(str);
