Hi everyone!
Can anybody tell me how to obtain the classical permutation matrix of binary variables?
for example given n=3 boolean variables A B C:
ABC
000
001
010
011
100
101
110
111
I hope there would be a command for this.
thank you!!

The easiest way to do this is with bin2dec. You can loop from 0 to 2^n-1 to get all combinations. To convert the character array back to a numeric vector you can simply use =='1'.

str2num is not a fix, it introduces a call to eval, which is completely unnecessary. Comparing to '1' will already convert to a numeric vector. You can also pass a vector to dec2bin:
n=3;
str=dec2bin(0:2^n-1,n);
H= str=='1';
disp(H)
