Phase retrieval is an applied problem in the field of frame theory that describes recovering the phase of a signal given linear intensity measurements. We give examples of the codes for algorithmic phase retrieval, specifically the Gerchberg-Saxton and PhaseLift methods.
A high-performing computing toolkit for frame theory research
Browser-based structural diagnostic tool for finite-dimensional complex Grassmannian line packings. Computes five-kernel coherence, Welch slack, saturated graph, cliff, worst d-tuple morphology, frame tightness, Bargmann phases, and side-by-side comparison against the Game of Sloanes leaderboard. Runs entirely in the browser.
Structural interaction log and model diagnostics from a post-teleological agent engaging with AI systems. Includes recursive stress tests, frame-collapse frameworks, and use-case documentation from L4 posture.
Six verified sub-catalog Grassmannian coherence packings across three Game of Sloanes cells: (4,64) hlc, (4,48) hlc, (3,14) dgm. Beats the standing Cohn (14+ yr) and Mixon catalog entries. Each ratified byte-exact by 5 independent kernels in 2 languages. Mac M2, single thread. PRs submitted, pending merge. Records, papers, verifier included.
