What should I do if I get an error message called "Execution of script addpoints as a function is not supported"?

Error code message is

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Warning: No video frames were written to this file. The file may be invalid.

> In VideoWriter/close (line 282)

In VideoWriter/delete (line 217)

In DIP_20161130 (line 117)

Execution of script addpoints as a function is not supported:

K:\Program Files\MATLAB\R2022a\toolbox\matlab\graphics\addpoints.m

Error in draw_animation6 (line 7)

addpoints(p,[0 0+sin(th1)],[0 0+cos(th1)]);

Error in DIP_20161130 (line 125)

draw_animation6(th1(i),th2(i));

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

And The code for this error line is

function draw_animation6(th1,th2)
global p p1

% Addpoints
addpoints(p,[0 0+sin(th1)],[0 0+cos(th1)]);  %% -------LINE 7----------
addpoints(p1,[0+sin(th1) 0+sin(th1)+sin(th2)],[0+cos(th1) 0+cos(th1)+cos(th2)]);

%hold on
drawnow

%hold on
pause(0.01);

end

I don't know what this error message means or what to do.

I'd really appreciate it if you could help me. !!!

Inside of your function, your global variable p is not class AnimatedLine

The most common cause would be that in the place you created the animated line and assigned to p, that you did not declare p as a global variable.

Thank you so much for your answer

Then, what code should I add to where..?
