Course objectives
The aim of the course is to acquaint students with the numerical methods used in physics calculations as well as in treatment of experimental and observational data. Acquired knowledge to practice their own solution to problems on the computer, in more complex cases, including the use of existing programming libraries.
Syllabus
  • Accuracy. Rounding errors and numerical methods. Representation of numbers in a computer. Strategy for reducing errors.
    Computational aspects. Programming languages ??, libraries programs. Making graphs.
    Solution of algebraic equations. The system of linear algebraic equations, Gauss elimination method. General algebraic equations. The method of dividing interval, secant method, Newton's method iteration. Newton's method in case of multiple roots of a system of equations with more unknowns.
    Approximation of functions. Interpolation polynomials (Lagrange, Hermite ). Instability extrapolation. Chebyshev approximation type (method of minimizing the maximum error). Definition and properties of Chebyshev polynomials. Chebyshev interpolation. Padeh approximation. Splines, natural splines. The method of least squares. Physical motivation, hypothesis testing.
