I am trying to use strcmp to compare 2 logical arrays, reading the notes, this cannot be used for logical arrays, only character arrays.
http://www.mathworks.com/help/techdoc/ref/strcmp.html
TF = strcmp(C1, C2)
As it stands i have 2 options, either:
1) find a function that will allow me to compare logical arrays.(No such look so far).
2) convert all the 1's to a specific letter and all my 0's to a different letter also, then i should be able to use strcmp. (But am unsure how to change specific data in an array.)

a=logical([1 0 1 1])
b=logical([1 0 1 1])
isequal(a,b)
ans=
1
a=logical([1 0 1 1])
b=logical([1 0 0 1])
isequal(a,b)
ans=
0

You cannot successfully strcmp logical values for no particular reason I can see. The comparison just returns false.
You can, however,
strcmp(char(C1),char(C2))

Thanks for your answers guys, i have figured it out.
It is similar to what Paul Silva was getting at. So thank you both.
I used the following in the end:
C = A & B;
As this is a logic compare instruction. (Logic AND) Which also ensures C is the same size 32x32 matrix as the objects A and B that are being compared.

That approach will not work if A and B are not the same size, and it is unable to detect locations where one of the two has a 0 but the other has a 1.
