Hi, I have a square matrix Q of dimension N and would like to generate the quadratic function $\sum_{i,j}q_{ij}x_i x_j$. The problem is how to say to Mathamatica that the variables names are x1, x2, etc. Is it possible to generate variables names in an automatic way? A possibility would be to generate manually a vector NN={x1, x2, x3, ....} of dimension N and then to pick NN[[i]] for the ith variable name, but imagine when N=1000... !! Thanks, Kim
