It is if that's how you plotted it. > What I am asking If I create a array like t=np.arange(0,31,.1) ,then what > is the corresponding array of f_t which agrees well with the previous > plot,i.e,for any t between t=0 to t=7, f_t will be determined by using a > straight line connecting (0,4) and (7,3) and so on. It sounds to me like you're asking how to do linear interpolation http://en.wikipedia.org/wiki/Linear_interpolation But that's a type of curve fitting, and you specifically said you're not asking about curve fitting -- so you've lost me. -- Grant Edwards grant.b.edwards Yow!
