Database-Backed Matrix Classes and Operations

Provides S4 classes and methods for storing dense and sparse matrices in 'DuckDB' databases. The package supports constructing database-backed matrices from base R and 'Matrix' objects, extracting slices and summaries, performing arithmetic and selected linear algebra operations, and materializing results for larger-than-memory workflows. It integrates with 'dbProject' to keep database paths, live connections, and lazy matrix tables synchronized across interactive analyses.

dbMatrix

{dbMatrix} is a core package in the dbverse library.

The goal of {dbMatrix} is to support larger-than-memory matrix computations.

Note: Work in progress! Bugs or unexpected behavior are likely to occur. We welcome user feedback and reporting issues on the Github page. ## Installation
