Objectifs

This course is an introduction to inverse problems, so that students can use simple data management and interpretation techniques. The aim is for them to know and to understand the underlying assumptions of the techniques used, to understand the importance of good management of measurement errors, and to be able to assess the impact of these errors on the solutions obtained.
