I want to compare these two vectors one by one. I want MATLAB to write as a result of it. for example,
with A(1)(1 here) If 1=B(1) the result should be 1/2, and if A(n)<B(1) the result should be 1, and A(n)>B(1) = 0.
It should compare all elements one by one and output its index in a new vector.

You mean like this?
A=[1 2 3 4 5 6 7 8 9 10];
B=4;
result=zeros(size(A));%pre-allocate
L= A<B ;result(L)=1;
L= A==B;result(L)=1/2;
disp(result)
1.0000 1.0000 1.0000 0.5000 0 0 0 0 0 0

A=[1 2 3 4 5 6 7 8 9 10] ;
B=4 ;
idx = A >= B
idx = 1×10 logical array
0 0 0 1 1 1 1 1 1 1
