I have a series of X and Y that some of Ys might be inf. Ys are changing in each loop there might be inf in them (more than one or none).
When I plot with plot(X,Y) function, it deos not show inf values. Any suggestion?

What do you mean by "Bump ^^"?
for example at x=1, y=inf and all other x and y are nonzero. I want at x=1 to add an inf point in the figure like this:Capture.JPG

"Bump" was merely pointing to the question I asked above.

Adam posted
y = randi(1e10, 1,100);
y(randi(100,1,15)) = inf;
plot(min(y, 2e10), 'o')
set(gca,'ytick',0:2e+09:2e10)
ytickLabels = get(gca,'YTickLabel');
ytickLabels{end} = 'inf x10^{10}';
set(gca, 'YTickLabel', ytickLabels)
His line
ytickLabels = get(gca,'YTickLabel');
creates a variable named ytickLabels. His line
ytickLabels{end} = 'inf x10^{10}';
then changes the last label to that particular string.
Then the line
set(gca, 'YTickLabel', ytickLabels)
tells MATLAB to change the YTickLabel property of the axes to the value stored in the variable ytickLabels
Adam's code does not attempt to use ytickLabels as a function. His code cannot generate the error message you indicate,
Cannot find an exact (case-sensitive) match for 'ytickLabels'
Please post a copy of the code you are using that generates that error message.
