I have been using fsolve to derive constants for a polynomial. These are presented clearly in blue, but I am unable to reference these numbers for further calculations other than by typing them in manually. e.g. output is:

{d = 520.9032305, c = .41478630e-1, b = -.84548378e-5, a = .125070852e-8}

 


fsolve({y[1]=a*x[1]^3+b*x[1]^2+c*x[1]+d,y[2]=a*x[2]^3+b*x[2]^2+c*x[2]+d,
> y[3]=a*x[3]^3+b*x[3]^2+c*x[3]+d,y[4]=a*x[4]^3+b*x[4]^2+c*x[4]+d},{a,b,c,d});
