[LABELS ENERGY ENERGYAFTER] = GCMEX(CLASS, UNARY, PAIRWISE, LABELCOST,EXPANSION)

Parameters:

• CLASS: A 1xN vector which specifies the initial labels of each of the N nodes in the graph

• UNARY: A CxN matrix specifying the potentials (data term) for each of the C possible classes at each of the N nodes.

• PAIRWISE: An NxN sparse matrix specifying the graph structure and cost for each link between nodes in the graph.

• LABELCOST: A CxC matrix specifying the fixed label cost for the labels of each adjacent node in the graph.

• EXPANSION: A 0-1 flag which determines if the swap or expansion method is used to solve the minimization. 0 == swap, 1 == expansion. If ommitted, defaults to swap.
