Vector

A linear algebra library written in TypeScript that focuses on generality, extensibility, and ease of use.

Features

  • Core:
    • Basic manipulation of vectors and matrices
    • Out-of-the-box support for number and ComplexNumber
    • Extensible to support general scalar types
  • Matrix Operations:
    • Matrix determinants
    • Matrix exponentials
    • Elementary row operations
    • Gauss-Jordan elimination
    • Eigenvalue / Eigenvector finding
  • Matrix Factorizations:
    • Cholesky Decomposition
    • LU Decomposition
    • QR Decomposition
    • Singular Value Decomposition
  • Applications:
    • Calculus: Differentiation via finite differences
    • Statistics: Least-Squares Regression for arbitrary model functions
    • Statistics: Principal component analysis
  • Machine learning models
    • Regularized linear regression
    • Logistic Regression
    • Support Vector Machines
  • And more to come!
