yline error for Matlab example

Hello Matlab Community,

I am having trouble to use yline command. Even if I try the matlab example, I receive the below error:

Code for example from yline documentation:

https://de.mathworks.com/help/matlab/ref/yline.html

fplot(@(x) log(x));
xlim([0 15]);
ylim([0 4]);
yline(3,'-','Threshold');

Addition to my question, I also tried the xline example and received a similar error. The link of example from xline documentation:

https://de.mathworks.com/help/matlab/ref/xline.html

xline(5,'--r');

What can I do to fix my line problem?

I am using matlab R2022b and it is newly updated.

Thank you in advance for your time and support.

First, you could have ‘overshadowed’ the line function somehow. To determine that, run this from a script or your Command Window:

which line -all

built-in (/MATLAB/toolbox/matlab/graphics/primitive/line)
/MATLAB/toolbox/coder/half/@half/line.p                    % half method

The result should be similar to the displayed result. If it says anything else (particularly ‘line is a variable’ or something similar) that could be the problem. The solution would be to re-name the user function or variable.

If that is not the problem, try running these from a script or your Command Window:

restoredefaultpath

rehash toolboxcache

If that still does not solve the problem, Contact Support.

Hello @Star Strider, thank you for your support.

Not

which line -all

but

restoredefaultpath 
rehash toolboxcache

solved my problem.

Thanks a lot!
