Looking for function

    1. The problem statement, all variables and given/known data
    I need to get a general function in 2 variables f(m,n). You can see a graphicon with charasteristic points:
    In the first example m=2 (m is period).

    In the next example m=3:

    For m=4:

    and so on.

    The task is to find a general function f(m,n) with these terms:
    The function has to be periodic.
    The function has to include those blue and red points in each example.
    The value of the function has to be f(m,n) =1 ONLY in blue points, and the value of the function has to be f(m,n)=0 ONLY in red points.

    The look of the function isn't important as long as it complies with previous terms.

    2. Relevant equations
    see above

    3. The attempt at a solution
    try to use absolute, trigonometric functions
