What is SymPy

From the web site: SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python.

Why use SymPy
  • Symbolic derivatives (optimization, nonlinear solvers, ...)
  • C++ Code generation (performance, portability, ...)
  • LaTeX Code generation (documentation, publication, ...)

Comparison of numerical methods

This post is devoted to te comparison of simulation results obtained by the following numerical methods:

  • Explicit and implicit Euler methods,
  • Trapezoidal rule,
  • Midpoint rule,
  • Discrete gradient method combined with PHS structure.

Results are given in Python code.
