The JuliaSymbolics Organization Roadmap We need new Computer Algebra Systems (CAS) for this new era of computing. We need a CAS that dispatches in the multiple ways we think. We need a CAS that scales exponentially like our problems. We need a CAS that integrates with our package ecosystem, letting …

You are basically asking for symbolic “matrix calculus”, I think: Matrix Calculus MatrixCalculus provides matrix calculus for everyone. It is an online tool that computes vector and matrix derivatives (matrix calculus).

Yes, it’s one of the next things @shashi is working on.

As a physicist, I’ve spent a little too much time in my life pasting (and then reformatting) expressions between Julia and Mathematica. Very excited about these developments!

Love it, I was waiting for something like this :slight_smile: :slight_smile: Do not underestimate however how important precise, complete but also accessible documentstion is. SymPy doc is so lovely!

Bill Helton (emeritus UCSD) has been developing a Mathematica package called NCAlgebra for noncommutative algebra. Maybe some inspiration can be found there (at least for those with an access to Mathematica, but perhaps there is also free some viewer for Mathematica notebooks).

Why would this be bad manners? There’s always space for people to praise others’ work and encourage them.

In SymPy you can use indexed objects . from sympy import * x = IndexedBase('x') n = symbols('n', Integer=True) i = Idx('i') j = Idx('j') u = Sum(S(1)/2 * log(x[i]), (i, 1, n)) du = u.diff(x[j]).doit() You can get rid of the piecewise result by imposing bounds on the indices, or by simplifying: re…

Is the intention for Symbolics.jl to eventually compete w/ CASs (SymPy, Mathematica, Maple etc)? SymPy already has >260k lines of code… Or is it more to supplement existing stuff? While I’m sure CAS can work better in Julia, this feels like an insanely ambitious project for an already insanely bu…

[image] Albert_Zevelev: While I’m sure CAS can work better in Julia, this feels like an insanely ambitious project for an already insanely busy organization. I really hope you have funding/labor/craziness to make this work It’s already been one of SciML’s biggest projects for the last year, …

Not the most productive comment, so somebody please let me know if it is not good discourse manners, but: wow. This is mind-blowing.
