Monotone Cubic Interpolation

Implementation for monotone cubic interpolation with the Hermite function through python3 and C++

Environment Setup

• python3
  • numpy
  • matplotlib (optional)
• C++
  • Standard c++11 or higher version is required.

Example

• Figure for the results via monotone cubic interpolation
  • # of original data points : 30
  • "" for interpolation : 500
