Dynamic Mode Decomposition (DMD) with Koopman operator theory extensions, powered by a Rust backend via 'extendr'. Provides standard DMD as described in Schmid (2010) , DMD with control for forced linear systems following Proctor, Brunton, and Kutz (2016) , Extended DMD with lifting functions, Hankel-DMD via time-delay embedding, Generalized Laplace Analysis for direct eigenfunction computation, and harmonic time averages and mesochronic harmonic plots for phase space analysis as developed in Mezic (2020) . Includes built-in area-preserving and chaotic maps for experimentation.

Provides a client for 'AstraeaDB', a graph database with vector search capabilities. Supports node and edge create, read, update, and delete operations, label and edge-type lookups, graph traversals (breadth-first search, depth-first search, shortest path), temporal (time-travel) queries, graph algorithms (PageRank, Louvain community detection, connected components, and degree and betweenness centrality), vector similarity search, hybrid graph-vector search, Graph Query Language (GQL) execution, and graph-based retrieval-augmented generation (subgraph extraction with large language model integration). Communicates with the 'AstraeaDB' server over a JSON-over-TCP protocol. An optional 'Apache Arrow Flight' transport is available for high-performance bulk operations when the 'arrow' package is installed.
