Latex2Sympy2 Extended

1.11.0 · active · verified Sat Apr 11

latex2sympy2-extended parses LaTeX math expressions and converts them into equivalent SymPy forms. It supports a wide range of mathematical constructs including arithmetic, common functions, calculus, and linear algebra. The current version is 1.11.0, with a release cadence reflecting active development and maintenance.

Warnings

breaking The library is not compatible with Python 3.13 due to the removal of 'typing.io'. It requires Python 3.12 or below.
Fix: Use Python 3.12 or an earlier version until compatibility is officially added.
deprecated The `latex2sympy2_extended.math_normalization.equations` module/functionality is deprecated as its handling is now integrated directly into the parser.
Fix: Remove direct calls to `math_normalization.equations` and rely on the parser's built-in handling.
gotcha When converting certain linear algebra expressions (e.g., determinants, transposed matrices, elementary transformations), the conversion process may involve irreversible calculations, meaning the resulting SymPy expression might not be algebraically identical to the original if interpreted purely symbolically.
Fix: Be aware of this limitation and verify results for complex linear algebra operations.
gotcha Comma-separated numbers are only supported in standalone forms (e.g., '1,233') and not within expressions (e.g., '1,233x').
Fix: Ensure that comma-separated numbers are used as standalone values or reformatted before passing to the parser if they are part of a larger expression.

Ensure you import from 'latex2sympy2_extended' and not the older 'latex2sympy2' or 'latex2sympy' packages.

Quickstart

This quickstart demonstrates how to import the `latex2sympy` function and use it to convert a common LaTeX derivative expression into its SymPy equivalent.

from latex2sympy2_extended import latex2sympy

# Define a LaTeX expression for a derivative
tex_expression = r"\frac{d}{dx}(x^{2}+x)"

# Convert the LaTeX expression to a SymPy expression
sympy_expression = latex2sympy(tex_expression)

print(sympy_expression)
# Expected output: Derivative(x**2 + x, x)
