Question: How to test for convexity

Hi,

I'm using Maple 14 and have a function in several variables, which I want to minimize. As far as I know, to guarantee that NLPSolve (from the Optimization package) is really finding a global minimum, this function must be convex.

What is the best way to test for convexity in Maple?

Thanks in advance,
