sympy_conversion

wrenfold.sympy_conversion.from_sympy(expr: Any, sp: Any | None = None) → Expr | MatrixExpr | BooleanExpr

Convert sympy expressions to wrenfold expressions. This method will recursively traverse the sympy expression tree, converting each encountered object to the equivalent wrenfold expression.

Parameters:

  • expr – A sympy expression.

  • sp – The sympy module. If None, the package sympy will be imported.

Returns:

The closest equivalent expression.

Raises:

TypeError – When a sympy object has no equivalent in wrenfold.

wrenfold.sympy_conversion.to_sympy(*args, **kwargs)

Overloaded function.

  1. to_sympy(expr: wrenfold.sym.Expr, sp: Optional[object] = None, evaluate: bool = True) -> object

Convert expression tree to sympy expressions.

Parameters:

  • expr – Scalar-valued expression.

  • sp – The sympy module. If None, the sympy package will be imported.

  • evaluate – Forwarded to sympy constructors as the evaluate argument. If true, sympy will canonicalize expressions.

Returns:

Equivalent sympy expression.

Raises:

wrenfold.sym.TypeError – If no equivalent expression type exists in sympy.

  1. to_sympy(expr: wrenfold.sym.BooleanExpr, sp: Optional[object] = None, evaluate: bool = True) -> object

Overload of wrenfold.sympy_conversion.to_sympy() that accepts BooleanExpr.

  1. to_sympy(expr: wrenfold.sym.MatrixExpr, sp: Optional[object] = None, evaluate: bool = True) -> object

Overload of wrenfold.sympy_conversion.to_sympy() that accepts MatrixExpr.
