herm_to_symmetrise()

STensor syten::STensorImpl::herm_to_symmetrise

(

STensor

in

)

Takes the hermitian conjugate and adapts the bases such that addition with the input tensor results in a symmetric tensor.

Crucially, this is not the same as simply taking the hermitian conjugate, i.e. it is not possible to contract the result of this operation with the input.

Remarks

This function is not autodifferentiable.
