Efficient iterative solutions to complex-valued nonlinear least-squares problems with mixed linear and antilinear operators
{{output}}
We consider a setting in which it is desired to find an optimal complex vector x ∈ C N that satisfies A (x) ≈ b in a least-squares sense, where b ∈ C M is a data vector (possibly noise-corrupted), and A (·) : C N → C M is a measurement operator. If ... ...
