ufunc Intro

This lesson is part of NumPy · All levels

Summary

Universal function (ufunc) is a function that works on all elements of an array element-wise at high speed because it is implemented in C. For example, np.add, np.subtract, np.multiply, np.sqrt, and np.mod. NumPy also provides checker ufuncs such as np.isnan and np.isinf for data cleaning needs.

Key points

Ufunc processes elements one by one without an explicit Python loop.
Examples of ufunc arithmetic: add, subtract, multiply, divide, power, mod.
The built-in ufunc includes square roots, logic, and abstraction.
Np.isnan and np.isinf are useful for checking invalid values such as NaN or inf.
