The first part of the course deals exclusively with discrete ,inverse problems, with a finite number of parameters. Some real ,problems, are naturally discrete, while others contain functions of a continuous variable and can be discretized if the functions under consideration are smooth enough compared to the sampling length, or if the functions can conveniently be described by their development ...
