[Numpy-discussion] quadratic function

  I have used both linear least squares and radial basis functions as a 
proxy equation, calculated from the results of computer simulations 
which are calculating some objective function value based on a number of 
varied input parameters.

As an alternative option I want to add a quadratic function so if there 
are parameters/variables x,y,z then rather than just having a linear 
function f=a+bx+cy+dz I'll have f=a+bx+cx**2 + dxy + .... I'd like to 
have the option not to include all the different second order terms.

Where should I start looking?
