How to compare two vectors element by element?

Question

I have two matrices: A=[1,2,3,4,5] and B=[1,2,3,4,6]. I need to compare elements of those matrix, and as a result I need to have binary matrix Result=[1,1,1,1,0], that means if A(i)==B(i) then Result(i)=1 else Result(i)=0.

I have tried with:

if (isequal (A,B))
   Result=1
else
   Result=0
end

I have tried: Result=sign(A,B)

I hope that you could help me please?

it gives me Result= 0, however i need the result is a matrix. — Guillaume, Aug 12 '16 at 13:32
yes I am sure, @StewieGriffin, it isn't a duplicate question. — Guillaume, Aug 12 '16 at 13:36
How is this not a duplicate? They are identical as far as I can see, only that the other one applies to two dimensions instead of one. Does [this answer](http://stackoverflow.com/a/2202651/2338750) not solve the problem? — Stewie Griffin, Aug 12 '16 at 13:37

A = [1,2,3,4,5]
B = [1,2,3,4,6]
Result = A == B

I thought you said `A == B` didn't work? – sco1 Aug 12 '16 at 13:39
A==B, just gives me Result = 0, but Result= A==B gives me the best Result=[0,0,0,0,1] – Guillaume Aug 12 '16 at 13:42

`A == B`; `ans = [1 1 1 1 0]` – sco1 Aug 12 '16 at 13:44
