Guidance notes
Numerical analysis is the area of mathematics and computer science that creates, analyses, and implements algorithms for numerically solving mathematical problems. Numerical analysis is required for applications including — but not limited to:
- simulations of physical systems
- machine learning
- data analytics
Numerical analysis is concerned with:
- floating-point arithmetic and the resulting accumulation of rounding errors (integer arithmetic which has different considerations)
- consideration of the numerical stability, condition numbers, accuracy, computational complexity and usability of algorithms that solve mathematical problems.
