This PR:
.mT
attribute for performing a batched matrix transpose on an array instance.Background
Discussion regarding the need for an
.mT
attribute can be found in gh-228.Notably, we cannot use the existing
.T
attribute for applying a transpose operation to a stack of matrices, as this would introduce an undesirable incompatibility in the array library ecosystem, where existing practice (see NumPy et al) is to reverse all dimensions for arrays having more than two-dimensions. Accordingly, in order to support applying a batched matrix transpose on an array instance, a new attribute is necessary.
