So firstly i have convert a string into decimal then i do a xor to it so as the result i have a logical result stored in the variable k.

```    word = 'TEST';
binary = dec2bin(word,8);
bin=binary(:)-'0';
k = xor(bin, t4(1:length(bin)));```

i tried to convert back using bin2dec function like :

```    w = xor(k, t4(1:length(bin)));
w=char(bin2dec(reshape(w,8,[]).')).';```

But got an error say that the Input must be a string. i think it is because the input are logical value. Can someone correct me? or show me how to convert back from logical to binary ?

Try

```w=char(bin2dec(reshape(num2str(w),8,[]).')).';
```
