Mathematical Functions

Module Mathematical Functions

Collection of the suppported, overloaded mathematical functions (e.g. sin, cos, exp, ..).

The ADTypes implement these functions as member functions. So in case the input a is an ADType, calling the respective member returns a new ADType with the calculated value (and its derivative representation). If the input a does not implement the mathematical function, a AttributeError is raised and we fall back to the numpy implementation.
