Implementation of geodesic on Stiefel Manifold

[Muhammad Ajmal]

Hello,

I have not been able to locate the geodesic function on Stiefel manifold in Pymanopt. Could someone please assist me?

Best regards

Ajmal

Hello,

In the matlab version of Manopt, it is implemented as part of stiefelfactory.m (see the code for M.exp in there, around line 200 or so in the file).

If it is not available in PyManopt, your best option is to post about it on the PyManopt github page. You or someone else could push a pull request to add that feature based on the Matlab code.

Best,

Nicolas
