how to manipulate for loop with a changing variable in an expression to get outputs

      I need  the syntax  to make  a changing variable *z* output  multiply each other sequentially 15 times for each  f (for loop) computation  as shown below and then display Y for each f stated.
      for f = [1 4 8 10];
      b = 2; c = 4;
      z = 200.*[1.1.*ones(1,1)  0.9.*ones(1,1)];%  repeated and multiplied sequentially  15 times for each findings of f
      Y = f*b*c*(z1*z2*z3...*z15); 
      disp(Y);      % display  Y  for  f=1,4,8,10
      end
