Re: [sympy] GSoC Idea Discussion

No, this isn't listed on the ideas page. I just thought it would be an interesting idea that could be implemented on a larger range of functions. If this isn't a good enough idea, I'd love to work on calculus-related projects such as Risch algorithm or other ODE related projects. Could you gui

Re: [sympy] GSoC Idea Discussion

If not, I know there happen to be a number of problems with respect to the 2/3 arg mul. I would also like to try and attempt to fix that from all the possible angles - fixing all the dependent code after considering the effects on downstream projects. On Friday, March 12, 2021 at 2:27:45 PM UTC

[sympy] How to test my code

I want to run my own version of the lti.py program file and see if it passes all the tests previously present in test_lti.py . But when I run the test_lti.py file, it takes the sympy module from the python interpreter installed on my computer. Can someone solve this issue or forward some links? I u

Re: [sympy] Re: Permutation documentation question

My thinking is expression in the transformations of the original list of items, [0,1,2,3]. If you first transpose the 2nd and third position you get [0,1,3,2] and then if you transpose 1st and 2nd position you get [0,3,1,2]. You'll see my name all over the docs for that module so if you can find

Re: [sympy] Re: Permutation documentation question

Hi Chris, The convention that I'm familiar with is that the notation (both cycle notation and the two-line notation) represents the exchange of *elements*, not positions. See for example http://www.math.caltech.edu/~2015-16/1term/ma006a/17.%20More%20permutations.pdf pp. 4--5. So my interpretat

[sympy] Re: How to test my code

This sounds as if it may be an issue with switching GIT branches. Are you modifying the file in a GIT branch or making a whole new file? Things should work if you modify the original file on a branch and run the tests on the branch. On Friday, March 12, 2021 at 3:12:20 AM UTC-6 deeps...@gmail.

Re: [sympy] Re: Permutation documentation question

If you have the list [1, 2, 3] and you permute positions 2 and 3, you get [1, 3, 2], then permuting positions 1 and 2 gives [3, 1, 2]. >>> list(Permutation(1, 2)(2, 3)) [0, 3, 1, 2] (the 0 is also included because Permutation assumes 0 indexing). Note the distinction between the permutation, writ

Hi again, Note also that GAP handles permutations identically to SymPy, and the manual states unambiguously that "GAP multiplies permutations from left to right!": https://college.cengage.com/mathematics/gallian/abstract_algebra/5e/shared/gap/gap_manual.pdf?URL=www.kau.edu.sa (p. 25). Again, th

Re: [sympy] Re: Permutation documentation question

I'm sure that changing the convention would be greatly frowned upon. The SymPy documentation clearly states ``` Caution: when the cycles have common elements between them then the order in which the permutations are applied matters. The convention is that the permutations are applied from *ri
