    Function approximation of piecewise function

    Hi,

    I'm trying to smooth a piecewise function in order to make the gradient continuous for an optimisation problem. I want to restore the main gradients in each of the piecewise components.

    The piecewise function is
    1. S = Y - N where Y-N > beta * Y
    2. S = beta * Y otherwise

    Can anyone point me in the right direction?

    Cheers,

    T.

    This looks unwise, but if you must do this I think more information is needed, like where does this function come from, what does it represent and exactly how are you going to use the smoothed version.
