sympy_conversion

wrenfold.sympy_conversion.from_sympy(expr: Basic | MatrixBase, sp: module | 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 used.

Returns:

The closest equivalent expression.

Raises:

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

wrenfold.sympy_conversion.to_sympy(expr: Expr | MatrixExpr | BooleanExpr, sp: module | None = None, evaluate: bool = True) → Basic | MatrixBase

Convert expression tree to sympy expressions.

Parameters:

  • expr – Scalar-valued expression.

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

  • 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.
