1. Overview

	This package provides improved implementations of the error function for
	MATLAB. It ships a MEX-file for calculating the	error function of real-
	valued numbers 5-6x faster than with the default MATLAB implementation.
	A second MEX-file and/or a companion M-file enhances the calculation of
	the error function for complex numbers. See "erfz.pdf" for implementa-
	tion details.


2. Requirements

	• An Intel Pentium II compatible computer or newer.
	• MATLAB 6.0 or newer running.


3. Installation

	Unpack the archive in a folder that is part of the MATLAB path. The error
	functions should reside in a '@double' folder to avoid potential data type
	conflicts.


4. Copyright

	This software is published as freeware. The author reserves the right to
	modify any of the contained files.

	You are allowed to distribute the functions as long as you deliver for free the
	entire package.

5. Warranty

	Any warranty is strictly refused and you cannot anticipate any financial or
