erf(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.

This MATLAB function returns the Error Function evaluated for each element of x.

(where N ∼ N(0, 1) N ∼ N (0, 1) is a standard normal) by the expression erf(x) = 2Φ(x 2–√) − 1 erf (x) = 2 Φ (x 2) 1. My question is: Why is it natural or useful to define erf erf normalized in this way? I may be …

Aug 15, 2016 · Furthermore, the maximum errors of the inverse logistic function (logit) and the probit function are bounded at .0802364.0802364 in the region [−0.841941, 0.841941] [0.841941, …

This MATLAB function throws an error and displays an error message.

Nov 3, 2015 · that is the value of the error function evaluated at x = 1/ 2–√ x = 1 / 2. It can however be interpreted in a different way if you consider the formulate I gave.

This MATLAB function returns the Complementary Error Function evaluated for each element of x.

This MATLAB function represents the complementary error function of X, that is,erfc(X) = 1 - erf(X).

Aug 25, 2016 · The function error() is not a standard API call. I suspect that your book is either talking about a library that provides this function, or it includes a library of its own that implements this function.

If you size it properly, then the function will appear constant with respect to your machine precision outside of this interval. Once you have a compact domain, you can know exactly how many Taylor …
