hotCpp = higher-order tensor interpolation implemented in C++

hotF90 = higher-order tensor interpolation implemented in F90

Rapsodia is a tool for the efficient computation of higher order derivative tensors. It consists of two parts.

1. A Python-based generator producing C++ or Fortran code for the forward propagation of univariate Taylor polynomials. This code yields efficiency gains via explcitly unrolled loops for a fixed derivative order and number of directions.

2. Implementations of the algorithm to interpolate derivative tensor entries from univariate Taylor coefficients in C++ and Fortran

This part of the documentation covers the C++ implementation of the higher-order tensor interpolation.
