See #1104 for the general problem/the idea of batched linear algebra (focussing on the case of matmul for batches of matrices).

This issue is intended to do the same for further linear algebra routines: QR, Cholesky, Eigh and SVD.

Expected behaviour:

  • QR, Cholesky, Eigh and SVD for batches of Matrices as in PyTorch if DNDarray is split along one of the batch-dimensions
  • NotImplementedError if DNDarray is split along the linear algebra dimensions
  • For QR this needs to be integrated in existing routine, for the others this can be done stand-alone (i.e. in new files heat/core/linalg/svd.py etc.)
