abs¶ metatensor.abs(A: TensorMap) → TensorMap[source]¶ Return a new TensorMap with the same metadata as A and absolute values of A. \[A \rightarrow = \vert A \vert\] If gradients are present in A: \[\nabla(A) \rightarrow \nabla(\vert A \vert) = (A/\vert A \vert)*\nabla A\] Parameters: A (TensorMap) – the input TensorMap. Returns: a new TensorMap with the same metadata as A and absolute values of A. Return type: TensorMap
