Weberf( X ) represents the error function of X . If X is a vector or a matrix, erf(X) computes the error function of each element of X .
WebAug 11, 2024 · Equation \ref{rest energy} is the correct form of Einstein’s most famous equation, which for the first time showed that energy is related to the mass of an object at rest. For example, if energy is stored in the object, its rest mass increases. This also implies that mass can be destroyed to release energy. WebJan 7, 2024 · Species in a chemical reaction is a general term used to mean atoms, molecules or ions. A species can contain more than one chemical element (HCl, for …
WebSpecifically, Erf ( x) = 2 ( Φ ( x 2) − Φ ( 0)) = 2 ( Φ ( x 2) − 1 2) = 2 Φ ( x 2) − 1. This shows how to express the Error Function in terms of the Normal CDF. Algebraic manipulation of … WebSep 25, 2024 · In the present chapter we shall need to make use of the error function erf a. This is the area under the gaussian curve from x = -a to x = + a: (4.1.2) erf a = 1 π ∫ − a + a e − x 2 d x. The area outside the limits x = ±a, which is the area under the two “tails” of the gaussian function, is sometimes called the complementary error function:
