- TensorRemove is a hack, come up with a long term rationalised approach to Complex vs. Scalar<Scalar<Scalar<Complex > > >
QDP forces use of "toDouble" to get back to non tensor scalar. This role is presently taken TensorRemove, but I
want to introduce a syntax that does not require this.
- Reductions that contract indices on a site should always demote the tensor structure.
norm2(), innerProduct.
- Result of Sum(), SliceSum // spatial sums
trace, traceIndex etc.. do not.
- problem arises because "trace" returns Lattice<TComplex> moving everything down to Scalar,
and then Sum and SliceSum to not remove the Scalars. This would be fixed if we
template specialize the scalar scalar scalar sum and SliceSum, on the basis of being
pure scalar.
* Optimise the extract/merge SIMD routines; Azusa??
- I have collated into single location at least.
