    Question n dimension quadratic

    The Problem
    This isn't the assignment itself: I want to be able to enter a function into the MATLAB command line.
    ie) >> Function = .....


    Equation
    An n-dimensional quadratic -
    eg)
    f(x1, x2, x3) = x1^2 + 2x2^2 + 3x3^2 + 2X1X2- 3X1X3 + 2X2X3

    Ideas
    Can't find anything on the internet. Tutorials are either too basic or too advanced.


    Your help is much appreciated

    Thanksin advance
