How to display a plot going to infinity?
显示 更早的评论
I am meant to plot the Dirac Delta function:
my attempt:
x = -30:1:30;
y = zeros(1,numel(x)); %sets all values initially to zero
y(x==0)= inf; % the point corresponding to x=0 is set to inf
plot(x,y,'d')
axis([-40 40 0 inf])
How can I get it to visually show it going up to infinity?

text(-41.,0.67,'~','Fontsize',20)
text(39,0.65,'~','Fontsize',20)
text(39,0.67,'~','Fontsize',20)
axis([-40 40 0 inf])
Adjust the text positions.....

Sorry I wasn't clear, I am looking to visually display the value of x=0 going to infinity like in this figure:

There are a couple of File Exchange contributions for creating plots with broken axes.
