I am trying to make a plot of the funktion f(x)=exp(x)/(exp(x)+1)
This is how I tried to do it:
x = [0:0.1:2];
y1 = exp(x)/(exp(x)+1);
plot(x, y1)
But for some reason I only get one value in y1.
I have tried changing the the funtion to something else, and it works fine.
I have tried to see if I wrote the function wrong by simply checking different numbers between 0 and 2 and it works fine.

Look up the "dot" operators for element-by-element operation instead of matrix operations...
"./" insread of "/"

Hi, check this code out, its the correct code.
%% YOUR CORRECT CODE
x = 0:0.1:2;
y1 = exp(x)./(exp(x)+1);
figure
plot(x,y1,'r--o','LineWidth',2)
