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);
