Validating the trained model with a provided trajectory

[rdspace]

This is more of a query rather than an issue.
So Once the model is trained, how do I validate the model with some random trajectory I provide.

So as an example I would like to test the trained model on a circular trajectory with the center of the circle at (200, 200) which is the base point of the link, and with a radius of 150 (so that all the trajectory points are reachable, as it would be within range of both the link lengths combined that is 200).

So I could just generate all the circular trajectory points by simple circle equation as follows,
r=150; % radius
C=[200 200]; % center
theta=0:2pi/360:2pi; % the angle
m=r*[cos(theta') sin(theta')]; % the points

Then say that I would like to test the trained model to follow all of these trajectory points.

How that can be done, as for now in your code, the testing is done with mouse pointer movement.

Any help will be gratefully appreciated.

Also If I would like to add the 3D aspect as shown in the attached figure, what would be the way to go forward?
