Basic linear algebra and computer programming. |
- Basic concepts of floating-point arithmetic. Conditioning of a problem. Numerical stability of an algorithm.
- Linear systems: direct methods (Gaussian eliminitations, LU-decomposition, Choleski) and iterative methods (Jacobi, Gauss-Seidel, SOR).
- Approximation of functions and data: polynomial and piecewise polynomial interpolation, splines, discrete least squares.
- Non-linear equations and systems: Newton's method and its discrete variants, fixed-point iteration.
- Numerical integration: Newton-Cotes formulas, Gaussian quadrature rules, composite rules.
- Initial value problems for ordinary differential equations: one-step methods (Runge-Kutta methods) and multistep (Adams) methods. Stiff problems.
