Don't understand what no "value element of matrix" means, precisely, but your expression in the if is missing a reference to an array by the subscripting expression. Something like
if (x(i,j) >=A && x(i,j) <B)
would serve to compare the elements of the array x to A and B presuming the latter are constants. Of course, w/ Matlab, you don't need the loop at all, simply
ix=(x>=A & x<B);
will return a logical array of True|False (1|0 numerically).

I believe something like this is what you want:
Matrix = randi(9, 5) % Create Data
A = 4;
B = 6;
Result = (Matrix >= A) & (Matrix <= B) % Logical Matrix
Matrix =
9 7 6 3 9
4 5 8 8 7
7 5 8 1 5
2 9 6 5 5
1 6 2 2 1
Result =
0 0 1 0 0
1 1 0 0 0
0 1 0 0 1
0 0 1 1 1
0 1 0 0 0
