Christopher,

Try

{a1, a2, a3, a4, a5} = {a1, a2, a3, a4, a5}  /. {a1 ->
0.00400772472374540367, a2 -> -1.90417580406264459*10^-6,
    a3 -> 499088.922439139537, a4 -> 1.31534993678125777*10^-9,
    a5 -> 7728.37550019371821}.

'/.' stands for ReplaceAll and carries out the substitution rules which are
returned by several functions like e.g. NonlinearFit.

Subject: [mg19091]  [mg19024] Conversion of output




Hello,

when using the NonlinearFit-function of Mathematica, I get an
output like

 {a1 -> 0.00400772472374540367, a2 -> -1.90417580406264459*10^-6,
    a3 -> 499088.922439139537, a4 -> 1.31534993678125777*10^-9,
    a5 -> 7728.37550019371821}

I'd like to convert this output to a vector with five elements
(containing the values of a1 to a5 shown above).

Can anybody tell me how to do this ?

Thanks,

Christopher Mack,
