一个关于数据聚类和模式识别的程序,在生物化学,化学中因该都可以用到.希望对大家有用,谢谢支持

				load iris.dat
				data = iris;
				k = 1;
				
				featureNum = size(iris, 2)-1;
				feature = iris(:, 1:end-1);
				output = iris(:, end);
				
				for i=1:featureNum,
					allCombination = combinat(1:featureNum, i);
					for j=1:size(allCombination,1);
						thisData = [data(:, allCombination(j,:)) output];
						looError = looknn(thisData, k);
						fprintf('Selected input: ');
						for k=1:size(allCombination,2),
							fprintf('%g ', allCombination(j,k));
						end
						fprintf(' ===> Leave-one-out error = %g\n', looError);
					end
				end
