what is a boolean in matlab

main.m
        ```matlab
        %declaring a boolean variable
        a = true; 

        %printing the value of boolean variable
        disp(a)

        %changing the value of boolean variable 
        a = false;

        %printing the new value of boolean variable
        disp(a)
        ```

        Output:
        ```
        1
        0
        ```

        In the above example, we have declared a boolean variable `a` with an initial value of `true`. We have then printed the value of `a` using the `disp` function, which gives the output `1` since `true` is equivalent to `1` in MATLAB. We have then changed the value of `a` to `false` and printed its new value using the `disp` function, which gives the output `0` since `false` is equivalent to `0` in MATLAB.
