GETCOST

Get classification cost matrix

   [COST,LABLIST] = GETCOST(W)

Returns the classification cost matrix as set in the classifier W.  An empty cost matrix is interpreted as equal costs for misclassification.  In that case COST = ONES(C+1) - EYE(C+1) is returned, if C is the number  of classes. Row C+1 and column C+1 in COST refer to unlabeld objects.  In LABLIST the class labels are returned.  Getcost will return [] when no costmatrix is defined.

If A has target labels an error is returned as in that case no classes  and thereby no costs are defined.
