OptiQ Solver

Auto-generated stub. Edit this file to add more details.

A component within QuatIca that solves quaternion Hermitian semidefinite programs using log-det barrier Newton methods with $\mu$-continuation.

Why It Matters

It introduces a specialized solver for a difficult class of optimization problems (quaternion Hermitian semidefinite programs) relevant to signal processing and potentially ML regularization.

Evidence

The library also includes OptiQ, which solves quaternion Hermitian semidefinite programs using log-det barrier Newton methods with μ-continuation.
