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.
