How do I randomize the value in a constant block for a local reset function for RL training

I am trying to train an RL Agent for a quadcopter model and for the same, I need to randomize the desired location of the drone which is a vector of 3 elements. I have followed the RL-Water Tank example( https://www.mathworks.com/help/reinforcement-learning/ug/create-simulink-environment-and-train-agent.html ) for the local reset function but I am not able to randomize the constant value in the same way. Please help.
Thanking You

Here I tried to test it by deliberately using a constant value.

The num2str([10 10 10]) evaluates to '10 10 10' without brackets which is what causes the problem. Instead, just put '[10 10 10]' directly in the last argument, like
setBlockParameter(in,blk,'Value','[10 10 10]')
