| Hi there,

| How can I store the coefficients from the Fit function as a list?

Hi LZ,

The built-in function *CoefficientList* 
(http://documents.wolfram.com/mathematica/functions/CoefficientList)does the 
trick. In the following example, say that poly stores a function returned by 
a *Fit* command:

In[1]:=
poly = -4.49313465504904 + 4.746130614134783*x -
   0.09995054089321051*x^2;

In[2]:=
CoefficientList[poly, x]

Out[2]=
{-4.49313465504904, 4.746130614134783,
  -0.09995054089321051}

Best regards,
