I need syntax to make z to be increasing and decreasing by 2% over 20 sections as inputs and display 20 outputs as shown below :
f = 100;
z = 200 ;% how to make it to be increasing and decreasing by 2 % over 20 sections
b = 2; c = 4;
Y = f*b*c*z;
disp(Y);

Is it necessary to use 20 sections? Why not using a for loop?
f = 100;
b = 2;
c = 4;
for i = 1:20
z = 200 * (1 - 0.02 * (i-10) );
Y = f*b*c*z;
disp(Y);
end
