    Re: projection onto a convex set

    we'll need a little more information than that. what set do the variables belong to? real numbers? integers? complex numbers? vectors? and what exactly are you trying to project? another set? a sphere? an entire space? does the projection have to be linear, or distance-preserving, or continuous?
