Hi guys,
I'm very new to matlab, so this might a rookie mistake. However, it seems that I have messed up some important part with the plot function. The program does not give my any kind of error messages, but still does not plot anything. What can I have done wrong and how do I fix this?
Best regards
My code:
close all
for t = -2:0.1:3
if (t<0 || t>1)
xvalue = 0;
end
if (t<= 1 && t>= 0)
xvalue = exp(2*t+1);
end
yvalue = -1*(xvalue) + exp(1);
hold on
figure(1);
plot(t, yvalue);
hold off
end
grid on;

try
scatter(t, yvalue);
You are making a whole bunch of one point plots each time you go through the loop (thus they are blank for plot). I would consider building an array in your loop and then plotting all the data at once, at the end.
