Hello all boosters,

I was wondering if a polynomial class has ever been proposed for boost ?

Hi Loïc, Sounds like you have a polynomial class you want to propose... What can I do with it (multiply, divide, derive, integrate, create a regression curve from a set of vectors,...) ? I would prefer a functional analysis toolkit which is not limited to just polynomials ("spirit for functional math", so to say). Something which feels like this: function f = ( _3 = sqrt(_1) * sin(_1 ^ _2)); BOOST_ASSERT(f.derive(_1).derive(_2) == f.derive(_2).derive(_1)); cout << "x2=f(x1;x3)=" << f.calculate<double>((_1 = 1, _3 = 2)) << endl; I'm aware that it's an advanced task to get it together. However, its usefulness would be undeniable then 8-). -- Tobias
