Hi,

If any one can tell me how to solve the nonlinear system sys:={x^2+y^2+z^2=4,x^2+y^2-z^2=4,x+y+z=0} by using fsolve command? I tried fsolve(sys,{x,y,z});, but there is no value returned. May I give fsolve an initial approxiamtaion of the solution ? If that is the case, what should I do?

 

Thanks in advance!
