Excellent piece of work!
Thanks to guys like Markus MATLAB is the best computing environment in the world!
Markus, could you add to the readme file releveant references (Munkres, Hungarian algorithms, assigment problem in general)?

Is 'assignmentoptimal(rectMatrix)' is the implementation of Munkres algorithm for rectangular case? It says it is Munkres algorithm but original algorithm is for square matrices. This one should be extended version for rectangular cases, right? Can you confirm this.
