Hi,
I try to find a method of doing the following in Mathematica.
I have some function y[x_]=a x^2 + b x + c
Now I want some list which hold values for a, b and c. that are dependend on some lower level values d, e and f.
vars1=[{d=1, e=4, f=6},{b=d+e, c=2f, a = d^2}]
vars2=[{d=2, e=3, f=7},{b=d+e, c=2f, a = d^2}]
vars3=[{d=5, e=5, f=1},{b=d+e, c=2f, a = d^2}]
and use these sets with the original function when I need it.
This line will not work as intended of course but I hope it makes it clear what I try to do. The key is I would like to not evaluate these values outside this vars, so the original function stays unevaluated.
Something like this I tried to do with either the functions Block or With, but both evaluate the values for a, b and c. I would like to make several such sets of variables without evaluating them so I can use them as desired, to plot the original function with several sets of vars.
