logical and for a condition in matlab

main.m
        For example, if you have two conditions `A` and `B` and you want to check if both of them are true or not, you can do it like this:

        ```
        A = 1 > 0;
        B = 2 < 3;

        if A & B
            disp('Both conditions are true');
        else
            disp('At least one condition is false');
        end
        ```

        In this example, `A` is true and `B` is also true, so the output will be: `Both conditions are true`.

        You can use the logical AND operator `&` for vectors and matrices as well where the operation is performed elementwise.

        ```
        A = [1 0; 0 1];
        B = [2 3; 4 5];

        C = A & B;

        % C = [1 0; 0 1];
        ```

        In this example, `C` is a logical matrix that contains the elementwise logical AND between `A` and `B`. The resulting matrix `C` contains logical 1 at places where both `A` and `B` are non-zero and logical 0 at other places.
