Linear algebra is a foundational branch of mathematics that deals with vectors, matrices, and linear transformations. It plays a critical role in fields like machine learning, physics, and engineering. Here's a breakdown of key topics:

Core Concepts 📚

  • Vector Spaces: Sets of vectors closed under addition and scalar multiplication.
  • Linear Transformations: Functions preserving vector addition and scalar multiplication.
  • Eigenvalues & Eigenvectors: Scalars and vectors that satisfy $ A\mathbf{v} = \lambda\mathbf{v} $.
  • Matrix Decompositions: Techniques like LU, QR, and SVD for breaking down matrices.

Applications 🌐

  • Data Science: Principal Component Analysis (PCA) relies on eigenvalues.
  • Computer Graphics: Transformations for 3D rendering and animation.
  • Quantum Mechanics: State vectors and operators in Hilbert spaces.
