What is the Error Function Calculator & How does it work?
The error function, denoted as erf(x), is a special function that arises in probability, statistics, and partial differential equations. It is defined as the integral of the Gaussian function:The error function is used in various fields such as quantum mechanics, signal processing, and control theory to model phenomena that follow a Gaussian distribution.
