latex2sympy

latex2sympy parses LaTeX math expressions and converts it into the equivalent SymPy form.

Installation

ANTLR is used to generate the parser:

$ antlr4 PS.g4 -o gen

Usage

In Python 2.7:

from process_latex import process_sympy

process_sympy("\\frac{d}{dx} x^{2}")
# => "diff(x**(2), x)"

Examples

|LaTeX|Image|Generated SymPy| |-----|-----|---------------| |x^{3}| $x^{3}$ | x**3| |\frac{d}{dx} |t|x| $\frac{d}{dx} |t|x$ |Derivative(x*Abs(t), x)| |\sum_{i = 1}^{n} i| $\sum_{i = 1}^{n} i$ |Sum(i, (i, 1, n))| |\int_{a}^{b} \frac{dt}{t}| $\int_{a}^{b} \frac{dt}{t}$ |Integral(1/t, (t, a, b))| |(2x^3 - x + z)|_{x=3}| $(2x^3 - x + z)|_{x=3}$ |z + 51
