Description

Opening a new issue regarding uniform_distribution's for:

  • GeneralizedStiefel,
  • GeneralizedGrassmann,
  • complex-valued versions of Stiefel/Grassmann/GeneralizedStiefel/GeneralizedGrassmann.

Question was raised (and discussed) in #141 while discussing uniform_distribution for the real-valued Stiefel and Grassmann.

Also related: #142 which implements real-valued Stiefel and Grassmann versions.

Contributor guide

Research direction
Study the existing uniform distribution implementations for real valued Stiefel and Grassmann in issues #141 and #142, then extend the approach to complex valued and generalized manifolds (GeneralizedStiefel, GeneralizedGrassmann). Understand the mathematical formulation of uniform distributions on these manifolds and implement them following the existing code patterns.
