QR decomposition, also known as QR factorization, is a matrix factorization technique that decomposes a matrix into the product of an orthogonal matrix and an upper triangular matrix.
Key Features
- Matrix factorization technique
- Decomposes a matrix into orthogonal and upper triangular matrices
- Used in solving systems of linear equations, least squares problems, eigenvalue computations, and more
Pros
- Provides a numerically stable method for solving various mathematical problems
- Useful in a wide range of applications in numerical analysis and scientific computing
- Can improve the efficiency and accuracy of computations involving matrices
Cons
- May be computationally expensive for large matrices
- Can be challenging to understand for beginners in linear algebra
- Orthogonal matrices are not unique in QR decomposition
