Everything you type at the command prompt is a program. It is just written in BASH, Windows batch language, or the language of what ever shell/prompt you are using.
There are also a million commands in Python :)
There are two ways I can think of to get derivatives of the eigenvalues: 1. Calculate Routh's stability criteria and get a set of symbolic constraints, the derivatives can be...
There is a new PR in SymPy that generates the set of symbolic constraints needed to guarantee stability: https://github.com/sympy/sympy/pull/27717. That produces the inequality constraints we need for a linear system...
I don't know but that is not relevant to this issue so I'm hiding it.
All of the pieces should be in place to implement this now: - #440 - #444 - https://github.com/sympy/sympy/pull/27717
Another way to reduce time is to give better initial guesses. We can even store a solution and give that as a guess.
You can save any value to a txt file with many different methods. NumPy has builtin ways to do this: https://numpy.org/doc/stable/reference/routines.io.html
Here is the output from a recent build on the readthedocs system, which is slower than running it locally: ``` computation time summary: - ../examples-gallery/plot_parallel_park.py: 128.56 sec 0.0 MB -...
Yes, you are. I'm just logging information here on the broader issue. I will get to all your PRs, but it just takes time.
