Hi Peter,
Thank you very much for your reply! To be honest, I'm still learning Python and SymPy. When I generated a cProfile report, I got the following results: https://github.com/LuisOfL/GSoC2025-SymPy/blob/main/cProfile.txt. It’s worth noting that I may have misunderstood the 25% — it refers to a specific function call, not the overall class. In the link I shared with you, the line 1 0.000 0.000 0.380 0.380 lagrange.py:174(form_lagranges_equations) was reduced from ~0.380 s to ~0.285 s in the cProfile output.
