Compute the difference between headings.

angle1 | AgentMatrix object representing the moving agents, or Numeric. Vector of angles. |
---|---|

angle2 | AgentMatrix object representing the moving agents, or Numeric. Vector of angles. |

range360 | Logical. If |

Numeric. Vector of the smallest angles in degrees
by which `angle1`

could be rotated to produce `angle2`

(i.e., the target heading).

This function does the opposite as the one in NetLogo where
`angle1`

is the target heading.

`angle1`

and `angle2`

must be of the same length or if different,
one of them must be of length 1.

Positive values mean clockwise rotations, negative value mean counterclockwise rotations.
