Phased Array Simulation script

Hi I saw this phased array video by matlab

https://youtu.be/9WxWun0E-PM?si=GPxVMjpNA7bPBBz2

At 15:55, it simulated the different steering angles of antennas from -90 degrees to +90 degrees. However it doesn't show on the video how he did it.

Additionally, not only do I want to know how to do a script on steering angles, I also want to know how the pattern changes as each element(antenna) is being displaced on the x,y,z plane. Not just static like the video.
