Why isn't my graph plotting?
显示 更早的评论
This was my input code:
x = [0:0.25:5];
y = exp(x)/(exp(x)-1);
plot(x,y)
And when I run it it just comes up with a blank set of axes with no actual graph on it, not really sure why this is so any help would be appreciated!

That is because using matrix right division (/) it is plotting onlly one point, and while this would work if it also plots markers, will not work to plot lines, that require at least two points in order to draw a line between them.
Using element-wise division (./) creates the necessary vector and draws the plot —
x = [0:0.25:5];
y = exp(x)./(exp(x)-1);
% ↑ ← HERE
plot(x,y)
