Ran in:
Starting in R2024b, the compassplot function can be used in place of compass to create arrows eminating from the origin of a polar axes. The PolarAxes class (introduced in R2016a) has many properties and several functions you can use to customize its appearance. Note that compassplot can be combined in a PolarAxes with other plots like polarhistogram, polarplot, polarscatter, etc.
t = linspace(pi/3,2*pi,10);
cp = compassplot(t,sin(t)); % new in R2024b
pax = gca % get a handle to the PolarAxes
pax =
PolarAxes with properties: ThetaLim: [0 360] RLim: [0 1] ThetaAxisUnits: 'degrees' ThetaDir: 'counterclockwise' ThetaZeroLocation: 'right' Use GET to show all properties
pax.ThetaZeroLocation = "top";

Adding to Grzegorz Knor's comment, I used the following to rotate my compass (see attached pictures)
view([+90 -90]);
This is what Bruce Raine's script does also only that he saves the inputs as az and el first

Try this code, the above code has the signs around the wrong way.
az = 90; % azimuth i.e. rotate around z-axis horizontally by 90 degrees
el = -90; % elevation negative, effectively looking beneath plot
view(az, el);
