Numerical Analysis : Approximation, Interpolation, Integration
5 credits
30.0 h + 22.5 h
Absil Pierre-Antoine;
Basic skills in numerical methods, as covered, for example, within  LFSAB1104 (Numerical methods).
Remark : LINMA2171 is the second part of a teaching programme in numerical analysis, of which LINMA1170 is the first part ; however, LINMA1170 is not a prerequisite for LINMA2171.

The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.
Main themes
  • Interpolation
  • Function approximation
  • Numerical integration

At the end of this learning unit, the student is able to :

  • AA1.1, AA1.2, AA1.3

At the end of the course, the student will be able to:

  • Implement, in concrete problems, the basic knowledge required from an advanced user and a developer of numerical computing software;
  • Analyze in depth various methods and algorithms for numerically solving scientific or technical problems, related in particular to interpolation, approximation, and integration of functions.

Transversal learning outcomes :

  • Use a reference book in English;
  • Use programming languages for scientific computing.

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
  • Polynomial interpolation: Lagrange's interpolation formula, Neville's algorithm, Newton's interpolation formula, divided differences, Hermite interpolation.
  • Interpolation by spline functions : cubic spline interpolation, B-splines.
