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
