I want to do something like h = f(g(x)) and be able to differentiate h, like h.diff(x). For just one function like h = cos(x) this is in fact possible and the documentation makes it clear. But fo...

I aim to write a multidimensional Taylor approximation using sympy, which uses as many builtin code as possible, computes the truncated Taylor approximation of a given function of two variables r...

Short version: I am interested in some Clojure code which will allow me to specify the transformations of x (e.g. permutations, rotations) under which the value of a function f(x) is invariant, so ...

Given the equation |x - 5| + |y| = 5, how can one solve it using SymPy? If I'm using a combination of solve() and Abs() it gives me this error solving Abs(x - 5) when the argument is not real o...

I'm trying to get Matlabs's MuPad as pretty and convenient as MathCad. Assume two variable assignments: x_a:=2*unit::mm; y_b:=5*unit::mm; and I want a prettyfied (typeset with Tex) output like ...

I need to manipulate expressions like 1 + sqrt(3) and do basic arithmetic like addition, subtraction, and division. I'd like the result to be in some sort of canonical form so that it can be ...

Using Sympy, say we have an expression f, which is a polynomial of the Symbol "x" (and of potentially other symbols). I would like to know what if there is an efficient way to drop all terms in f...

These days I am trying to redo shock spectrum of single degree of freedom system using Sympy. The problem can reduce to find maximum value of a function. Following are two cases I cannot figure out...

The equations I am working with in this problem contain exponentials. For this reason, after differentiating they appear again pretty much unchanged apart from additional constants and other factor...

Does anybody know of any resources (books, classes, lecture notes, or anything) about the general theory of computer algebra systems (e.g. mathematica, sympy)? "Introductory" materials are p...

There are quite a few algebra solvers and simplifiers on the web (for example, the decent one at algebra.com). However, I'm looking for something I can plug into C# as part of a larger projec...

In sympy I have an integral which returns a Piecewise object, e.g. In [2]: from sympy.abc import x,y,z In [3]: test = exp(-x**2/z**2) In [4]: itest = integrate(test,(x,0,oo)) In [5]: itest Out[...

The Symbolism library overloads arithmetic operators. Although it's written in C# I can use it from F#: open Symbolism let x = new Symbol("x") let y = new Symbol("y") let z = new Symbol("z") pri...

I'm creating a CAS (Computer Algebra System) in PHP, but I'm stuck right now. I am using this website. Now I wrote a tokenizer. It will convert an equation like this: 1+2x-3*(4-5*(3x)) to this:...

I convert list to matrix in Maxima in following way: DataL : [ [1,2], [2,4], [3,6], [4,8] ]; DataM: apply('matrix,DataL); How to do it the other way ? How to convert given matrix DataM into list...

General I'm looking for a library that is able to do exact calculations on large finite fields such as GF(2128)/𝔽2128 and GF(2256)/𝔽2256. I listed the features that I need and the features...

In my research group, we have different people doing algebraic modelling in different symbolic tools such as Symbolic Toolbox in Matlab and Sympy in Python. These models are then typically exported...

I'm looking for a library or computer algebra system that will help compute operations on polynomials in the ring F_2[x_1, ..., x_n] / <f^2 - f> where F_2 is the 2-element finite fie...

I was wondering if symbolic computation in Computer Algebra System (such as symbolic toolbox in Matlab, Mathematica) and functional programming related and how? Does the former belong to the ...
