AT Passmethods

Passmethods are usually written in C for the best performance, but they may also be written in python or Matlab for prototyping.

The same passmethods are used by both the Matlab and python interfaces, ensuring a strict equality of tracking results in both version.

AT comes with a set of passmethods covering most needs, but it is very simple to add a custom passmethod.

• "Small angle" passmethods
• "Exact" passmethods
