I am working with simulink quadcopter project (asbQuadcopter) and I am trying to implement a control with deep reinforcement learning.
When i validate the environment, i have this problem:
Warning: Could not evaluate MaskDisplay commands of block 'asbQuadcopter/Visualization/Extract Flight
Instruments/V': Undefined function 'ports' for input arguments of type 'double'.

There is a undefined function in your one of the functions, if you share it here, it can be controlled.

Hi, thanks for the reply.
After several tests, I think I understand the problem. I was using this incorrectly in my function:
in = in.setVariable('init.euler', [0 0 0]);
in = in.setVariable('init.angRates', [0 0 0]);
Instead, I used this:
blkPt = 'nonlinearAirframe/Nonlinear/6DOF (Quaternion)';
in = in.setBlockParameter(blkPt,'eul_0', '0.01 .* rand(1,3)');
