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:
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:
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!
