Symbolic Simplifications

einconv.simplify 

simplify(equation: str, operands: List[Union[Tensor, Parameter]]) -> Tuple[str, List[Union[Tensor, Parameter]]]

Simplify an einsum expressions.

Parameters:

  • equation (str) –

    Einsum equation.

  • operands (List[Union[Tensor, Parameter]]) –

    Einsum operands.

Returns:

  • str –

    Simplified einsum equation.

  • List[Union[Tensor, Parameter]] –

    Simplified einsum operands.
