Dear All,

i suggest you try to use fsolve for this example , type fsolve in your comand window for an exaple of this type of function.but also it seems you have a system of two equations with more unknown which might lead to the system being ill conditioned, when using fsolve.So try two check in the optimization toolbox for examples of methods you can try.
