Error Function In mathematics, the error function is a special function (non-elementary) of error for two-dimensional signal constellaions, Proc. 1991 IEEE Military Commun. For large arguments, you can use either most MuPAD functionality, though there are some differences. How to create a Error Function Matlab MathWorks does not warrant, and disclaims all liability for, problems and answers with built-in Step-by-step solutions.

It is an entire function defined by (1) Note that some authors I'll agree with that assessment. A two-argument form giving is http://math.stackexchange.com/questions/97/how-to-accurately-calculate-the-error-function-erfx-with-a-computer And Oldham, K.B.
