High Dimensional Numerical and Symbolic Calculus // Efficient C++
optimized functions for numerical and symbolic calculus as
described in Guidotti (2022) doi:10.18637/jss.v104.i05. It
includes basic arithmetic, tensor calculus, Einstein summing
convention, fast computation of the Levi-Civita symbol and
generalized Kronecker delta, Taylor series expansion,
multivariate Hermite polynomials, high-order derivatives,
ordinary differential equations, differential operators
(Gradient, Jacobian, Hessian, Divergence, Curl, Laplacian) and
numerical integration in arbitrary orthogonal coordinate
systems: cartesian, polar, spherical, cylindrical, parabolic or
user defined by custom scale factors.
