I have ecountered a problem recently.It's something about 'complex nonlinear least square'. For instance,we want to minimize object function
y = min|3+4i - x^2|^2 ,where i = sqrt(-1),x is a variable
How can i get 'x' by using matlab function 'lsqnonlin'?
If there are more variables,how can i figure this out?
Anticipating your reply,thanks!
