Hello, I am new to sympy, and I am really impressed by the web demo at live.sympy.org.I am trying to replicate that shell's ability to understand latex maths notation, and I have been unsuccessful. I have combed through both sympy and sympy-live without understanding how live.sympy.org parses

Hi Duncan, To the best of my knowledge SymPy is unable to parse LaTeX. We are however able to generate it; this is what you're seeing on live.sympy.org. You can look at our latex printing by downloading our source and checking out the sympy/sympy/printing/latex.py file. I think it would be aweso

What SymPy Live does is return the LaTeX string of expression using the LaTeX printer (accessible through the latex() function), and then passes that to MathJax, which converts it to a printed expression. Any string output is passed to MathJax, so even if you just enter a string, it will be parsed

You can do it with subs or replace, but the proposed way is a little cleaner. It fits nicely with the concept of replacing a (mathematical) function with it's value. See the other discussion on this list about it. Aaron Meurer On Wed, May 23, 2012 at 9:41 AM, krastanov.ste...@gmail.com wrote:
