用matlab写的遗传算法分割程序

				function f=target(T,M)
				dT=double(T);
				[U,V]=size(T); W=length(M);f=zeros(W,1);
				for k=1:W
				s1=0;I=0;s2=0;J=0;
				for i=1:U
				    for j=1:V
				        if T(i,j)				            s1=s1+dT(i,j);I=I+1;
				        end
				        if T(i,j)>M(k)
				            s2=s2+dT(i,j);J=J+1;
				        end
				    end
				end
				p1=s1/I;p2=s2/J;
				f(k)=I*J*(p1-p2)*(p1-p2)/(256*256*256*256);
				end
