latex2sympy parses LaTeX math expressions and converts it into the equivalent SymPy form.
ANTLR is used to generate the parser:
antlr-4.7.2-complete.jar PS.g4 -o gen
or
java -jar antlr-4.7.2-complete.jar PS.g4 -o gen
In Python 2.7:
from latex2sympy import process_sympy
process_sympy("\\frac{d}{dx} x^{2}")
# => "diff(x**(2), x)"| LaTeX | Image | Generated SymPy |
|---|---|---|
x^{3} |
x**3 |
|
| `\frac{d}{dx} | t | x` |
\sum_{i = 1}^{n} i |
Sum(i, (i, 1, n)) |
|
\int_{a}^{b} \frac{dt}{t} |
Integral(1/t, (t, a, b)) |
|
| `(2x^3 - x + z) | _{x=3}` |
