Generalized Barycentric

Some articles on generalized barycentric:

Slack Variable - Embedding in Orthant
... Further information Orthant and Generalized barycentric coordinates Slack variables give an embedding of a polytope into the standard f-orthant, where f is the number of constraints (facets of the polytope) ... Slack variables are dual to generalized barycentric coordinates, and, dually to generalized barycentric coordinates (which are not unique but can all be realized), are uniquely determined, but cannot all be ... Dually, generalized barycentric coordinates express a polytope with n vertices (dual to facets), regardless of dimension, as the image of the standard -simplex, which has n vertices ...

Famous quotes containing the word generalized:

    One is conscious of no brave and noble earnestness in it, of no generalized passion for intellectual and spiritual adventure, of no organized determination to think things out. What is there is a highly self-conscious and insipid correctness, a bloodless respectability submergence of matter in manner—in brief, what is there is the feeble, uninspiring quality of German painting and English music.
