Hello, 

 

I am pretty new to Maple and Im trying to find the parameters of an equation using some kind of fit routine but I can only find such a routine to fit an expression to data and not vice versa.

my equation is as follows

 

epsilon(E):= a0 + a1*ln(E) + a2*ln(E)^2 + a3*ln(E)^3

 

I do have data for E which I imagine I need. 

 

E:= {121, 244, 344, 411, 444, 778, 867, 964, 1085, 1112, 1212, 1299, 1408} all in keV :)

 

Any suggestions/help would be much appreciated, although I am new to the program so go easy on me :) 

 

 

Cheers
