Nice with a problem that is not purely mathematical!
Using the parameters for Least Squares Fit(1) from Wikipedia, I get values that differ from yours by up to 2 MeV (except for Li-7, where I get 38, while you get 34). Do you use a different parameter set, or have I made a mistake?
I apologize, I messed up the polarity. Should be fixed now.
Thanks. I now pass every test except 6:
bindingEnergy({'Tl-203','Pb-208','Po-209','Ra-228'})
ans =
1596 1628 1632 1750
>> be
be =
1595 1628 1633 1749
Any ideas?
I assume you are rounding at the end. Before rounding
[1595.950245381877 1628.458256218912 1632.283183807810 1750.279872731407]
I checked that my Z and N are correct, coefficients are correct, last term is correct. All answers should be correct.
I get the answers in the test suite.
My fault. Somehow I was still testing against the old test values. Sorry for the inconvenience.
