I'm using this code to start but hasnt worked. patch command is giving error and not sure how to resolve it. Please help.
w0 = 1 ;
w1 = 0.5 ;
N = 5 ;
ww = linspace(w1,w0,N) ;
W = [fliplr(ww) ww] ;
ar=0.866; % Aspect ratio for equilateral triangle
h=ar*W;%height of triangle
for i = 1:length(W)
x=[0 W W/2];%x coordinates of vertices
y=[0 0 h];%y coordinates of vertices
patch(x,y,'white')
set(gca,'Color','k','xticklabel',[],'yticklabel',[])
drawnow
pause(0.1)
end

Try this
w0 = 1 ;
w1 = 0.5 ;
N = 5 ;
ww = linspace(w1,w0,N) ;
W = [fliplr(ww) ww] ;
ar=0.866; % Aspect ratio for equilateral triangle
h=ar*W;%height of triangle
fig = figure();
ax = axes();
set(ax,'Color','k','xticklabel',[],'yticklabel',[])
ax.XLim = [0 1];
ax.YLim = [0 1];
p = patch([0 0 0], [0 0 0], 'w');
for i = 1:length(W)
x = [0 W(i) W(i)/2];%x coordinates of vertices
y = [0 0 h(i)];%y coordinates of vertices
p.Vertices = [x.' y.'];
drawnow
pause(0.1)
end

I am glad to be of help!
Try this
w0 = 1 ;
w1 = 0.5 ;
N = 5 ;
ww = linspace(w1,w0,N) ;
W = [fliplr(ww) ww] ;
ar=0.866; % Aspect ratio for equilateral triangle
h=ar*W;%height of triangle
n = 200; % number of triangles
area = 20; % 10x10 square for all the triangles
triangle_locations = area*rand(n, 2); % location of triangles
fig = figure();
ax = axes();
set(ax,'Color','k','xticklabel',[],'yticklabel',[])
ax.XLim = [0 area];
ax.YLim = [0 area];
p = gobjects(1, n);
for i=1:n
p(i) = patch([0 0 0], [0 0 0], 'w');
end
for i = 1:length(W)
for k = 1:n
x = [0 W(i) W(i)/2] + triangle_locations(k, 1);%x coordinates of vertices
y = [0 0 h(i)] + triangle_locations(k, 2);%y coordinates of vertices
p(k).Vertices = [x.' y.'];
end
pause(0.1)
end
