    Getting high values in a function

    Hello,
    The equation for computing the coefficients of a minimum 4-term
    "Blackman-harris" window is:
    w(n)=a0-a1*cos(2pi*n/N)+a2*cos(2pi*2n/N)-a3*cos(2pi*3n/N)

    where:
    N/2<n<N/2
    and the window length is
    L=N+1
    The coefficients for this window are
    a0 = 0.35875
    a1 = 0.48829
    a2 = 0.14128
    a3 = 0.01168
    My question:
    I want that the function will get high values rapidly. In fact, that
    most of the values will be near the max., but in the same template of
    the function above.
    can you help me?

    No, you will have to run that past us again, what you are asking is almost completely incomprehensible.

    Why not just use a Tukey window?
