Plotting a red asterisk on a certain point

Hello MATLAB community,
I am trying to figure out how to label a specific point with a red asterisk on a 3D plot that I have. I attached a picture of the 3D plot that I get when I run my code.
There are two .m files that I put in the same folder in order to produce my specific plot: Problem_1.m and Potential.m (I attached them both). The main script that I run to produce the plot is the Problem_1.m file.
I have a 3D plot and I need to put a red asterisk on the [95 95] coordinate (or what I simply name as "loc" in my code) on my 3D plot. I tried using "markers" and "MarkerIndices" but it would always give me an error or give me something that I wasn't looking for.
I was wondering if anyone has had some experience with this. I would really appreciate your insight on it.

I am not certain what result you want.
Try this:
figure ();
meshc(x,y,z(x,y));
hold on;
plot3(loc(1), loc(2), z(loc(1),loc(2)),'r.', 'markers', 30);
txt2 = '\leftarrow Location of Bot';
I replaced your plot call with a plot3 call.
Experiment to get the result you want.
