Dear Steph,

I attached all necessary codes as m-files.

Maybe there is a typo in your function "fn_BBR_GPL_RMSE()"?  In short:

   Dcalc = D = D0 + D1*t.^m;
   SRE = (D-Dcalc)./D;

In this case "SRE" is always zero, as "Dcalc = D" and no progress seems
to happen.  Furthermore "D" seems to be an input parameter of
"fn_BBR_GPL_RMSE()", which is unused then.

HTH,
Kai
