Is it possible to solve the below equation in fsolve? If so please help with it...
There are n nodes and only W terms are unknown. Iteration is to be continued till tolerance is less than 10^-4
qi*qu+qi*alpha*Wi = (alpha*qu*Wi/U)- (G/m^2) * (W(i-1)*qu-2*Wi*qu+W(i+1)*qu+alpha*Wi*W(i-1)-2*Wi^2*alpha+alpha*Wi*W(i+1));
After each iteration value of G varies as Gn=Go/(1+(Go*dw/dx)/tau)^2;

I am not familiar with using optimization techniques in matlab. Please guide me with this. I have solved it using Newton's method. But i need to validate the answer. 

Thanks and Regards,
