mkl_sparse_qr_reorder, how to get permutation and rank

Hi 

I would like to use the Sparse QR solver from MKL.

Is there any way I can get the permutation from the pivot reordering (mkl_sparse_qr_reorder) step?

Also, is there any api to get the rank?

Thanks

Bryn

Hi Bryn!

 

Currently we don't have an API for returning either permutation or rank. If this feature is important for you, I suggest submitting a feature request.

 

Let us know if you need directions how to do that (and some more appropriate person than me will help you with that).

 

Best,
Kirill

Hi

 

Thanks for the information. I was thinking of adding a wrapper for the MKL Sparse QR to the Eigen library.

However, to make it support the same features as the native QR solver, and the SuiteSparse QR solver, access to the permutation and rank would be required.

If you can send me instructions how to request this feature that would be great.

Thanks

Hi,


Thank you for suggesting the feature. A similar request has already been reported to the developers. They are working on it. 


We are closing this thread for now. Kindly raise a new thread if you need any help, as this thread will no longer be monitored by Intel.
