Applications in Numerical Analysis

While SVD is fundamentally a linear algebra concept, it has powerful applications in numerical analysis:

1. Low-Rank Approximations: Creating compact representations of large matrices
2. Pseudoinverse Calculation: Solving ill-conditioned or singular linear systems
3. Image Compression: Reducing storage requirements while preserving key information
4. Noise Reduction: Filtering out components with small singular values
5. Computational Methods: Numerical stability in various matrix computations

The numerical implementation of SVD uses algorithms such as the Golub-Reinsch method or the Jacobi method, which balance computational efficiency with numerical stability.
