7492,Decomposition of a doubly stochastic matrix as a convex sum of permutations (Birkhoff–von Neumann Theorem),ncohen,mhansen,"As the title says, the Birkhoff–von Neumann Theorem (http://en.wikipedia.org/wiki/Birkhoff%E2%80%93von_Neumann_Theorem) says that any doubly stochastic matrix ( http://en.wikipedia.org/wiki/Doubly_stochastic_matrix ) can be written as a convex sum of permutations.
This patch requires several other patches to be applied first ( or merged into Sage ) :
* #8364
* #8166 (non-optional matching function !)
