[CA,CB] = ComputeC_Metric(PopA,PopB) ComputeC_Metric: Computes the C metric between two Pareto set approximations INPUTS PopA: First population, Each row corresponds to a vector PopB: Second population, Each row corresponds to a vector OUTPUTS CA: C(A,B) Proportion of vectors in PopB which are dominated by at leat one vector in PopA CB: C(B,A) Last version 2/26/2009.
