At some point we might want to have a POCS partial fourier filling.
Even if we use an iterative reconstruction algorithm, this can be used to provide a better x0 as far as I know:
It uses the assump…

Thanks for the great package. I am interested in fitting GPs using the Variational Fourier Features framework described in [Hensman et al. 2018](https://www.jmlr.org/papers/v18/16-579.html). From quic…

Tried to run the "example" in `projection_backprojection_cycle.py`.
After adjusting it to make it run on some local data, I get the following error:

Hello, I recently read one of your research papers. Could you please provide the data set for FWI-F?
I wish you all the best in your work!

We need a way to update the smaps internally while learning k-space trajectory.
This can get complicated and it is worth starting a discussion on this.
Basically, we need a way to estimate and upd…

Dear @rayosborn , while using nexpy for 3D-dPDF analysis, I have a question about the fourier transform applied in the nxreduce step.
