Dear NR users,
I need to solve two equations iteratively to reach self-consistently. The are mutiple variables (20-30 parameters) that could be changed in order to reach the self-consitency.

I could get this done in xls by "solver" utility (easily defing a objective function and minimize it change the parameters)

would you please kindly give me a hint that which routine I can use in oder to do the same in c++.

Many thanks
Amir
