abs

metatensor.abs(A: TensorMap) → TensorMap

Return a new TensorMap with the same metadata as A and absolute values of A.

$$A\to =|A|$$

If gradients are present in A:

$$\mathrm{\nabla }(A)\to \mathrm{\nabla }(|A|)=(A/|A|)\ast \mathrm{\nabla }A$$

Parameters:

A (TensorMap) – the input TensorMap.

Returns:

a new TensorMap with the same metadata as A and absolute values of A.

Return type:

TensorMap
