Mathematical functions with automatic domain (numpy.emath)
Mathematical functions with automatic domain (numpy.emath)
Note
numpy.emath is a preferred alias for numpy.lib.scimath, available after numpy is imported.
Wrapper functions to more user-friendly calling of certain math functions whose output data-type is different than the input data-type in certain domains of the input.
For example, for functions like log with branch cuts, the versions in this module provide the mathematically valid answers in the complex plane:
>>> import math >>> from numpy.li
