Here's an example that may be of interest that uses Sympy in the context of a scientific application.
This Jupyter notebook derives the defining equations for cubic spline coefficients (in tridiagonal matrix form), substitutes those equations into those for a tridiagonal solver (not derived, just taken from Wikipedia), and generates a templated C++ function. https://github.com/QMCPACK/qmc_algorithms/blob/master/Wavefunctions/CubicSplineSolver.ipynb The additional code generation bits are here: https://github.com/QMCPACK/qmc_algorithms/blob/master/Wavefunctions/codegen_extras.py More generally, I've been working to make a stronger connection between symbolic representations of expressions and the code that implements them. The example here generates production code, but a less intrusive route (which is used more frequently) is to create values for unit testing. So far, the process I've decided to use is to create a Jupyter notebook with a derivation or explanation of some expression. The notebook is manually converted to a python script which is run to create the code or the unit tests. This script is checked into the repository along with the generated code or tests. The above notebook was converted into this script in the main code repository: https://github.com/QMCPACK/qmcpack/blob/develop/src/Numerics/codegen/gen_cubic_spline_solver.py And the generated results are stored here: https://github.com/QMCPACK/qmcpack/blob/develop/src/Numerics/SplineSolvers.h (The notebooks are kept in a separate repository from the main code because this is still experimental. The manual conversion of the notebook to a standalone script is an unfortunate step, but the standalone script is easier to use and store for reproducibility.) -- You received this message because you are subscribed to the Google Groups "sympy" group.
