How can I plot all these graphs using the if statement?

 d=-26.5:1:1973.5;
  if (0 < d) & (d <=52)
        e = d*0.05;
  elseif (d > 1000)
    e = d*0.45-130.5;
  elseif (440 < d <=1000)
    e = d*0.40-80.5;
  elseif (235 < d <=440)
    e = d*0.30-36.5;
  elseif (117 <d) & (d<=235) 
    e =d*0.20-13;
   else (52< d) & (d<117)
    e =d*0.12-3.64;
  end

 plot(d,e)

Hello, Your variable e should be a vector. I will try with a for loop

for i = 1:2001
d(i)=i-27.5;
if (0 < d(i)) & (d(i) <=52)
      e(i) = d(i)*0.05;
elseif (d(i) > 1000)
  e(i) = d(i)*0.45-130.5;
elseif (440 < d(i) <=1000)
  e(i) = d(i)*0.40-80.5;
elseif (235 < d(i) <=440)
  e(i) = d(i)*0.30-36.5;
elseif (117 <d(i)) & (d(i)<=235) 
  e(i) =d(i)*0.20-13;
 else (52< d(i)) & (d(i)<117)
  e(i) =d(i)*0.12-3.64;
end
end
plot(d,e)

Thank you for the answer. Can I plot the different conditions, ie. the different plots of the elseif?

Sure, just create different variables or something like that:

plot(d(1:50),e(1:50));

Thanks a lot
