Description

Program compare two methods of interpolation:

• spline interpolation
• lagrange interpolation (with and without chebyshev nodes)

It compares them by printing approximated function.

Settings

In yaml file, you can configurate path to csv file with given functions and number of nodes to approximate function (take every x node).

main_params:
  filepath: './data/MountEverest.csv'   # path for file
  step: 21                              # get every step'th point

Examples

• Spline interpolation:

• Lagrange interpolation with evenly spaced 20 nodes, which cause Runge's phenomenon:

• Lagrange interpolation with 20 Chebyshev nodes:
