Hi all !

I am programming an application in which I need to find the minimum of a list of x and y. i.e. The minimum of a paraboloid for example or any other polynomial.

I am currently using the module Math::Polynomial and it does return the minimum of the list as well as the equation representing it.

My problem is, I need to know the x value where the minimum was found, not only the minimum value.

Is there a module that would send back the minimum and its associated x or a module with which I could solve an equation of the type y = n*x^n + n1*x^n1 + ...+ a*x^2+b*x+c (y is known, we're looking for x)?
