comparison src/DistanceMetric.cpp @ 69:696f6e7f2f31 refactors

distYSize no longer needed, and some tidying and checks

 
     int featureSize = f1.size();
     assert(int(f2.size()) == featureSize);
     
     for (int i = 0; i < featureSize; i++) {
+        assert(f1[i] >= 0);
+        assert(f2[i] >= 0);
         d += fabs(f1[i] - f2[i]);
         sum += f1[i] + f2[i];
     }
 
     if (sum == 0)
