    matrix-api-stable Pre-release

    jakeISAC released this 2026-02-10 14:32:38 +01:00 | 4 commits to stable since this release

    Matrix Library Release Notes

    Overview

    This release delivers bug-free and optimized matrix operations, with a focus on correctness, performance, and memory efficiency. The implementation is now stable for testing and usage. The project structure has been revised for better modularity, featuring multiple CMake configurations to streamline builds and dependencies.

    Key Improvements

    1. Matrix Operations

    • All core matrix operations are now fully validated and optimized.
    • Functions like find_invertible_submatrix are correct and functional, but not yet fully optimized. These are marked for further review.

    2. Block-Lanczos Algorithm

    • Introduced the first implementation of the block_lanczos algorithm, optimized for large-scale computations (hopefully 😅)

    3. Memory Efficiency

    • Rewrote multiply, add, and subtract using std::forward to support both l-values and r-values, allowing for either referencing or consuming other matrices. This reduces temporary matrix allocations, improving memory usage and performance.

    4. Project Structure & Build Automation

    • Revised project structure with multiple CMake configurations for better modularity and maintainability.
    • Added an run.sh script to automate the build process, simplifying setup and deployment.

    Future Work

    • Overload inverse, scalar_multiplication, and determinant to support consuming matrices directly.
    • Implement Macaulay matrix and polynomial operations in future releases.
