Dear Friends: I am using Fit within a function, and I want it to produce only a list of coefficients, without the variables. For example, if I plug into fit the following: Fit[{{1,2,3},{4,5,6},{7,8,9}},{1,x1,x2},{x1,x2}], Mathematica produces: 1.55556+0.555556 x1+0.444444 x2 I want to get only the following list: {1.55556,0.555556,0.444444} It seem awfully simple, but I haven't managed. How can I do it? Thanks Francisco
