Possible matlab bug with text() function?

I'm having issues with the text function. I am copying your example from the documentation, and I get the following error:
"Subscript indices must either be real positive integers or logicals."
Here is the example:
x = 0:pi/20:2*pi;
y = sin(x);
plot(x,y)
text(pi,0,'\leftarrow sin(\pi)')
I am using Matlab 2013a. Very simple example, not sure why I can't replicate the documentation example. Thank in advance!

When you name variable as the same name as the function this happens.
clear text plot sin % not sure which function you’re shadowing , but it definitely is a reason

If this recurs, set an error breakpoint and run your code. When you receive the error, check if you are in a function named text.m (which would be shadowing the built-in text function.) If you are not, post the full text of the error message (all the text displayed in red, not just the "Subscript indices must either be real positive integers or logicals." part) and it may provide the information needed to determine the cause.
