High Performance Scientific Computing with C 1.3: Interpolation and Extrapolation

The video tutorial covers interpolation and extrapolation, focusing on linear and polynomial interpolation techniques. It explains how interpolation fills in data between points and how extrapolation extends data beyond known points. The video includes coding examples for linear and polynomial interpolation, highlighting the risks of extrapolation, especially when predicting future data. The tutorial emphasizes the importance of understanding the limitations of these methods, particularly in fields like finance.
