Efficient Iterative Solutions to Complex-Valued Nonlinear Least-Squares Problems with Mixed Linear and Antilinear Operators

Tae Hyung Kim, Justin P. Haldar

We consider a setting in which it is desired to find an optimal complex vector $\mathbf{x}\in {\mathbb{C}}^N$ that satisfies $\mathcal{A}(\mathbf{x})\approx \mathbf{b}$ in a least-sq…
