How to plot a function in a for loop?

n=3;

for i=1:n+1 %this loop returns 4 curves, I want to plot them on a single graph

f{i} = @Bezier;

B=Bezier(n,i-1);

end

%I also want to plot the sum of the 4 curves (i.e. the curve that was generated at i=1 + the one at i=2...etc) (Their sums should be equal 1 across the range)

%This is the function code mentioned above

function [B]=Bezier(n,i)

figure; hold on

u=0:0.001:1;

B=factorial(n)/(factorial(i)*factorial(n-i))*u.^i.*(1-u).^(n-i); %bezier curves function

plot(u,B,'.')

end

%I can combine the curves in the function file but I don't know how to do it when I am calling the function

%and the sum of all graphs at any point should equal 1

function main
  n = 3;
  u = 0:0.001:1;
  for i = 1:n+1 %this loop returns 4 curves, I want to plot them on a single graph 
    B{i} = Bezier(u,n,i-1);
  end
  plot(u,[B{1};B{2};B{3};B{4};B{1}+B{2}+B{3}+B{4}])
end

function B = Bezier(u,n,i)
  B = factorial(n)/(factorial(i)*factorial(n-i))*u.^i.*(1-u).^(n-i); %bezier curves function
end

Thank you, Torsten!
