Projectors

  • DRE.m Dictionary Redundancy Elimination
  • DREOr.m uses Dre method to produce and orthogonal basis from D
  • DREOrp.m uses Dre method to produce and orthogonal basis Q from D
  • ObliProj.m constructs an oblique projection matrix onto the span of the columns of V along the span of the columns of Wp
  • OptObliProj.m regularizes the oblique projector by truncation of singular values
  • OrthProj.m construct an orthogonal projection matrix onto the span of the columns of D.
  • RegObliProj.m regularizes the oblique projection of f onto span of V along span of WC by truncation of singular values
All the presented routines are described in detail in our very provisional manual (ps,pdf).
