Why won't this plot?

%% Section 1: Initalization of Variables 

%increments of x
x = -4:1:-1;
%
%The function we are given
y = x + (1 ./ (x.^2-1));








%% Section 2: Processing
plot(x,y)
axis([-15 15 0 15])


%I want to be able to see the y function appraching the verticle asymptote '-1' from the left but my function wont graph

[Asad (Mehrzad) Khoddam]

First, use more points:

x = -4:.1:-1;

Then remove the axis limil:

% axis([-15 15 0 15])

Thank you so much!

The problem are the y-axis limits in the axis call.

Comment-out the axis call (as I do here) and you will immediately see the problem.

plot(x,y)
% axis([-15 15 0 15])

.

Thank you so much! It fixed my graph, but if I needed the x axis to be labeled from -15, to 15, how can I do that without breaking my code?

[Star Strider]

use xlim rather than axis:

xlim([-15  15])

.

It worked great! Thanks!

As always, my pleasure!
