Hi, every one!
I have an "Exceed equation group" like this :
(xi-x)*(xi-x)+(yi-y)*(xi-y)+(zi-z)*(zi-z)+ai=h;
where x,y,z,h,is unbeknown, and xi,yi,zi,ai,is known, i=6;
I wanna get a solution using nonlinear least-square approach; If someone give me a advise or send me source code (C++),I will appreciate him very much!
