MATLAB: How to set Color Data for Interpolated shading

interpolationpatch

I wrote a function to visualize some values on an object made of 24 brick elements:
function plottings(quantity)
  load('Mesh.mat', 'nds','elms')
  load('Specifications.mat','ELEMENT')
  x=nds(:,1);
  y=nds(:,2);
  z=nds(:,3);
    vertex_matrix =[x y z];
    faces_matrix=[];
    for i=1:ELEMENT
    face = [elms(i,1) elms(i,2) elms(i,6) elms(i,5);
            elms(i,2) elms(i,3) elms(i,7) elms(i,6);
            elms(i,3) elms(i,4) elms(i,8) elms(i,7);
            elms(i,4) elms(i,1) elms(i,5) elms(i,8);
            elms(i,1) elms(i,2) elms(i,3) elms(i,4);
            elms(i,5) elms(i,6) elms(i,7) elms(i,8)];
     faces_matrix= vertcat(faces_matrix,face);          
    end
    FaceVertexCData=quantity;
    patch('Vertices',vertex_matrix,'Faces',faces_matrix,...
          'FaceVertexCData',hsv(8),'FaceColor','interp')
    view(3)
    axis equal  
    end
…but Matlab doesn't want to interpolate shading and writes: Warning: Color Data is not set for Interpolated shading How should I write the code to pass that warning? or…what should I use instead of patch()?

fill3() works perfectly
