Course content

This course gives an introduction to the theory and applications of piecewise polynomials represented by B-splines. In the first part the focus is on basic properties and algorithms of B-splines in one variable, and various approximation methods using these. Subsequently the theory and methods are extended to functions in multiple variables/dimensions, such as parametric curves and tensor products. In the last part of the   course, the focus is on theoretical properties of B-splines, such as approximation properties and stability.


Learning outcome

After completing the course you know:

  • the basic properties and theory of B-splines;
  • how to implement basic algorithms for B-splines, such as evaluation, knot-insertion and interpolation;
  • how to use B-splines in practice, e.g. how to interpolate data in one or several variables.
  • how to present, on a scientific level, a short thesis on a chosen topic of relevance, selected in collaboration with the lecturer
