How to enable grid?

I'm trying to display grid lines on my figure using "grid on" but MATLAB keeps showing me there's an error at my line with "grid on". Anyone knows why this is so? I got the following code from MathWorks but it's not working.

x = rand(50,1);
y = rand(50,1);
scatter(x,y)
grid on

Your code runs for me without error.

Do you have a variable or user function of your own named grid?

To find out, run this from the Command Window:

which grid -all

The result should only be (for your version of MATLAB, I am running R2017a):

C:\Program Files\MATLAB\R2017a\toolbox\matlab\graph2d\grid.m

If you get anything else, that will tell you what the problem is. The solution is to rename your user function or variable to something else.
