System of eqs
Hi,
given the following system,
$\displaystyle
\begin{aligned}
v(t_1) &=& b_1 + b_2e^{t_1/b_3} + b_4e^{t_1/b_4} \\
v(t_2) &=& b_1 + b_2e^{t_2/b_3} + b_4e^{t_2/b_4} \\
v(t_3) &=& b_1 + b_2e^{t_3/b_3} + b_4e^{t_3/b_4} \\
v(t_4) &=& b_1 + b_2e^{t_4/b_3} + b_4e^{t_4/b_4} \\
\end{aligned}
$
where times $\displaystyle t_1,\dots,t_4$ and measurements $\displaystyle v(t_1),\cdots,v(t_4)$ are known, find constants $\displaystyle b_1,\dots,b_4$.
I have not had much about nonlinear systems, but perhaps Newton's would work well enough for something like this. What do you guys think?

Sure. It looks a bit different, but I think it would work well for your application.

Thanks for the quick reply!

You're welcome. Have a good one!
