How to make SVM with three group or multiple class

i want make classification SVM with 3 group. but i know classification SVM only match for 2 group or class. There is a way that can make SVM classification with 3 group or class? This is my code :

GLCM2 = graycomatrix(I3,'Offset',[4 4]);
  stats = graycoprops(GLCM2,{'contrast','homogeneity','energy','Correlation'})

    a = stats.Contrast;
    b = stats.Correlation;
    c = stats.Energy;
    d = stats.Homogeneity;

    set(handles.edit1, 'String',a);
    set(handles.edit2, 'String',b);
    set(handles.edit3, 'String',c);
    set(handles.edit4, 'String',d);

    load class_uji2.txt;// document text class or group with three class {0,1,2}
    load data_uji2.txt;// document text data glcm result
    uji1=data_uji2(:,1:2:3:4);
    massa = svmtrain(uji1,class_uji2)

    uji = svmclassify(massa, [a b c d])
    if uji == 0
        hasil = 'Normal'
    else if uji == 1
  hasil = 'Biasa'
  else
        hasil = 'kanker'
    end
  end

    set(handles.edit5, 'String',hasil);
