Symbolic Math in Julia?

Also, consider the Nemo.jl library which they claim is faster than alternatives like SageMath.

SymPy Package works fine, it brings Python's Sympy functionality into Julia via PyCall.

SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python and does not require any external libraries.

Now, looking at http://pkg.julialang.org/ one could find more candidates to perform symbolic mathematics in julia:

• SymEngine.jl

  Julia Wrappers for SymEngine, a fast symbolic manipulation library, written in C++.

• Symata.jl

  a language for symbolic computations and mathematics, where, for the most part, "mathematics" means what it typically does for a scientist or engineer.

• SymPy.jl

  Julia interface to SymPy via PyCall

Also:

• LinearExpressions.jl

  Linear symbolic expressions for the Julia language
