Java error function erf

A formula which yields erf ( x) to at least 22 decimal. tion- dependent diffusion equation can be obtained with the aid of the inverse error function,. Calculates the error function erf( x) and complementary error function erfc( x). You can use the ERF function to find the probability ( p) that a normally distributed random variable with mean 0 and standard deviation will take on a value less than X. public static class Gamma. Erf extends java. Methods inherited from class java. Object clone, equals,. This page provides Java code examples for org. The examples are extracted from open source Java. error function double p = Erf. Erfc( ) function is used to find the complementary error function of the given input ( x – parameter) in Go language. The standard math package of Go programming language has Erfc( ) function.
