Im triying to plot a surface on the top face of a cylinder using surface command, when I ran the code I get the surface on the squre that block the the face and not only on the face- my code:
theta =0:0.01*pi:2*pi; r=0.8;
x=r*cos(theta); y=r*sin(theta); f=(1:1:4);
V=[x' y'];
Patch=patch('Faces',f,'Vertices',V,'FaceColor', [171 104 87]./255);
C=Patch.FaceColor;
xd = get(Patch, 'XData')';
yd = get(Patch, 'YData')';
z0=zeros(1,length(xd));
zf=0.1*ones(1,length(xd));
Vx_ud(:,1)=xd; Vx_ud(:,2)=xd; Vy_ud(:,1)=yd; Vy_ud(:,2)=yd;
Vz_ud(:,1)=z0; Vz_ud(:,2)=zf;
ud=patch(Vx_ud,Vy_ud,Vz_ud,C);
for i=1:length(xd)-1
Vx_s(:,i)=[xd(i) xd(i+1) xd(i+1) xd(i)];
Vy_s(:,i)=[yd(i) yd(i+1) yd(i+1) yd(i)];
Vz_s(:,i)=[0 0 0.1 0.1];
end
Vx_s(:,length(xd))=[xd(end) xd(1) xd(1) xd(end)];
Vy_s(:,length(xd))=[yd(end) yd(1) yd(1) yd(end)];
Vz_s(:,length(xd))=[0 0 0.1 0.1];
s=patch(Vx_s,Vy_s,Vz_s,C,'EdgeColor','none');
th_DPatch=[ud, s];
I=imread('road.jpg');
Z=0.1*ones(201);
Face=surface(x,y,Z,EdgeColor="none");
set(Face,'CData',I,'FaceColor','texturemap');

theta =0:0.01*pi:2*pi; r=0.8;
x=r*cos(theta); y=r*sin(theta); z=zeros(size(x));
% simple patch for base
p_base =patch(x, y, z, [171 104 87]./255); hold on
% cylinder
[xc, yc, zc] = cylinder(r, length(theta)-1);
cc = repmat(reshape([171 104 87]./255, 1, 1, 3), size(xc));
surf(xc, yc, zc*0.1, cc, 'EdgeColor', 'none'); view(3)
% simple patch for base
p_top =patch(x, y, z+0.1, [171 104 87]./255);
